The Data Connector for Oracle and Hadoop does not apply time zone information to these Oracle data-types. The Data Connector for Oracle and Hadoop correctly imports this timestamp as: 2am on 3rd October, This data consists of two distinct parts: when the event occurred and where the event occurred.
When Sqoop without The Data Connector for Oracle and Hadoop is used to import data it converts the timestamp to the time zone of the system running Sqoop and omits the component of the data that specifies where the event occurred.
The Data Connector for Oracle and Hadoop retains the time zone portion of the data. Multiple end-users in differing time zones locales will each have that data expressed as a timestamp within their respective locale. When Sqoop without the Data Connector for Oracle and Hadoop is used to import data it converts the timestamp to the time zone of the system running Sqoop and omits the component of the data that specifies location.
The timestamps are imported correctly but the local time zone has to be guessed. If multiple systems in different locale were executing the Sqoop import it would be very difficult to diagnose the cause of the data corruption.
Sqoop with the Data Connector for Oracle and Hadoop explicitly states the time zone portion of the data imported into Hadoop. The local time zone is GMT by default. You can set the local time zone with parameter:. This may not work for some developers as the string will require parsing later in the workflow. The oraoop-site-template. The value of this property is a semicolon-delimited list of Oracle SQL statements.
These statements are executed, in order, for each Oracle session created by the Data Connector for Oracle and Hadoop. This statement initializes the timezone of the JDBC client. It is recommended that you not enable parallel query because it can have an adverse effect the load on the Oracle instance and on the balance between the Data Connector for Oracle and Hadoop mappers. Some export operations are performed in parallel where deemed appropriate by the Data Connector for Oracle and Hadoop.
See "Parallelization" for more information. When set to this value, the where clause is applied to each subquery used to retrieve data from the Oracle table.
The value of this property is an integer specifying the number of rows the Oracle JDBC driver should fetch in each network round-trip to the database. The default value is If you alter this setting, confirmation of the change is displayed in the logs of the mappers during the Map-Reduce job. By default speculative execution is disabled for the Data Connector for Oracle and Hadoop. This avoids placing redundant load on the Oracle database.
If Speculative execution is enabled, then Hadoop may initiate multiple mappers to read the same blocks of data, increasing the overall load on the database. Each chunk of Oracle blocks is allocated to the mappers in a roundrobin manner. This helps prevent one of the mappers from being allocated a large proportion of typically small-sized blocks from the start of Oracle data-files. In doing so it also helps prevent one of the other mappers from being allocated a large proportion of typically larger-sized blocks from the end of the Oracle data-files.
Use this method to help ensure all the mappers are allocated a similar amount of work. Each chunk of Oracle blocks is allocated to the mappers sequentially. This produces the tendency for each mapper to sequentially read a large, contiguous proportion of an Oracle data-file. It is unlikely for the performance of this method to exceed that of the round-robin method and it is more likely to allocate a large difference in the work between the mappers.
This is advantageous in troubleshooting, as it provides a convenient way to exclude all LOB-based data from the import. By default, four mappers are used for a Sqoop import job.
The number of mappers can be altered via the Sqoop --num-mappers parameter. If the data-nodes in your Hadoop cluster have 4 task-slots that is they are 4-CPU core machines it is likely for all four mappers to execute on the same machine. Therefore, IO may be concentrated between the Oracle database and a single machine. This setting allows you to control which DataNodes in your Hadoop cluster each mapper executes on. By assigning each mapper to a separate machine you may improve the overall IO performance for the job.
This will also have the side-effect of the imported data being more diluted across the machines in the cluster. HDFS replication will dilute the data across the cluster anyway. Specify the machine names as a comma separated list. The locations are allocated to each of the mappers in a round-robin manner. If using EC2, specify the internal name of the machines.
Here is an example of using this parameter from the Sqoop command-line:. This setting determines behavior if the Data Connector for Oracle and Hadoop cannot accept the job. Set the value to org. The expression contains the name of the configuration property optionally followed by a default value to use if the property has not been set.
A pipe character is used to delimit the property name and the default value. The oracle. This is the equivalent of: select "first name" from customers. If the Sqoop output includes feedback such as the following then the configuration properties contained within oraoop-site-template. For more information about any errors encountered during the Sqoop import, refer to the log files generated by each of the by default 4 mappers that performed the import. Include these log files with any requests you make for assistance on the Sqoop User Group web site.
The oraoop. Check Sqoop stdout standard output and the mapper logs for information as to where the problem may be. Questions and discussion regarding the usage of Sqoop should be directed to the sqoop-user mailing list. Before contacting either forum, run your Sqoop job with the --verbose flag to acquire as much debugging information as possible. Also report the string returned by sqoop version as well as the version of Hadoop you are running hadoop version.
The following steps should be followed to troubleshoot any failure that you encounter while running Sqoop. Problem: When using the default Sqoop connector for Oracle, some data does get transferred, but during the map-reduce job a lot of errors are reported as below:. Solution: This problem occurs primarily due to the lack of a fast random number generation device on the host where the map tasks execute.
On typical Linux systems this can be addressed by setting the following property in the java. The java. Alternatively, this property can also be specified on the command line via:. Problem: While working with Oracle you may encounter problems when Sqoop can not figure out column names. This happens because the catalog queries that Sqoop uses for Oracle expect the correct case to be specified for the user name and table name.
Problem: While importing a MySQL table into Sqoop, if you do not have the necessary permissions to access your MySQL database over the network, you may get the below connection failure. Solution: First, verify that you can connect to the database from the node where you are running Sqoop:. Add the network port for the server to your my. Set up a user account to connect via Sqoop. Grant permissions to the user to access the database over the network: 1.
Issue the following command:. While this will work, it is not advisable for a production environment. We advise consulting with your DBA to grant the necessary privileges based on the setup topology. When the driver option is included in the Sqoop command, the built-in connection manager selection defaults to the generic connection manager, which causes this issue with Oracle. If the driver option is not specified, the built-in connection manager selection mechanism selects the Oracle specific connection manager which generates valid SQL for Oracle and uses the driver "oracle.
Solution: Omit the option --driver oracle. OracleDriver and then re-run the Sqoop command. BIT, which Sqoop by default maps to Boolean. Sqoop User Guide v1. Table of Contents 1. Introduction 2. Supported Releases 3.
