Hi there, Does sqoop2 support specialized connectors for microsoft SQL server? Or does it rely on generic jdbc connector?
I see conflicting information here - https://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/latest/CDH5-Installation-Guide/cdh5ig_sqoop2_configure.html under Installing the Microsoft SQL Server JDBC Driver Download the Microsoft SQL Server JDBC driver from http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774 and copy it to the /var/lib/sqoop2/ directory. For example: $ curl -L ' http://download.microsoft.com/download/0/2/A/02AAE597-3865-456C-AE7F-613F99F850A8/sqljdbc_4.0.2206.100_enu.tar.gz' | tar xz $ sudo cp sqljdbc_4.0/enu/sqljdbc4.jar /var/lib/sqoop2/ ---------------------------------------------------------- and here - https://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/latest/CDH5-Installation-Guide/cdh5ig_sqoop_vs_sqoop2.html Connectors for all major RDBMS: Not supported. Workaround: Use the generic JDBC Connector which has been tested on the following databases: Microsoft SQL Server, PostgreSQL, MySQL and Oracle. This connector should work on any other JDBC compliant database. However, performance might not be comparable to that of specialized connectors in Sqoop. ------------------------------------------------------------------------- I am able to import table from microsoft sql but the export fails as follows - The export fails during transfer from stage table to target table. <JT stderr logs> 2014-07-15 19:33:11,681 [main] INFO org.apache.sqoop.connector.jdbc.GenericJdbcExportDestroyer - Job completed, transferring data from stage table to destination table. log4j:ERROR Attempted to append to closed appender named [maprfsTLA]. 2014-07-15 19:33:11,933 [main] ERROR org.apache.sqoop.connector.jdbc.GenericJdbcExecutor - Got SQLException while migrating data from: reg_stage to: reg com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'SELECT'. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:216) at com.microsoft.sqlserver.jdbc.SQLServerStatement.getNextResult(SQLServerStatement.java:1515) at com.microsoft.sqlserver.jdbc.SQLServerStatement.doExecuteStatement(SQLServerStatement.java:792) at com.microsoft.sqlserver.jdbc.SQLServerStatement$StmtExecCmd.doExecute(SQLServerStatement.java:689) at com.microsoft.sqlserver.jdbc.TDSCommand.execute(IOBuffer.java:5696) at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(SQLServerConnection.java:1715) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeCommand(SQLServerStatement.java:180) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeStatement(SQLServerStatement.java:155) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeUpdate(SQLServerStatement.java:642) at org.apache.sqoop.connector.jdbc.GenericJdbcExecutor.migrateData(GenericJdbcExecutor.java:91) at org.apache.sqoop.connector.jdbc.GenericJdbcExportDestroyer.moveDataToDestinationTable(GenericJdbcExportDestroyer.java:55) at org.apache.sqoop.connector.jdbc.GenericJdbcExportDestroyer.destroy(GenericJdbcExportDestroyer.java:39) at org.apache.sqoop.connector.jdbc.GenericJdbcExportDestroyer.destroy(GenericJdbcExportDestroyer.java:26) at org.apache.sqoop.job.mr.SqoopDestroyerExecutor.executeDestroyer(SqoopDestroyerExecutor.java:65) at org.apache.sqoop.job.mr.SqoopNullOutputFormat$DestroyerOutputCommitter.commitJob(SqoopNullOutputFormat.java:70) at org.apache.hadoop.mapred.Task.runJobCleanupTask(Task.java:1102) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:333) at org.apache.hadoop.mapred.Child$4.run(Child.java:282) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1117) at org.apache.hadoop.mapred.Child.main(Child.java:271) </JT stderr logs> - Additional Info: - The issue is re-producible - Import from MSSQL works fine. - Steps to re-produce: - Import a MSSQL table using sqoop2 - Try to export the same table to MSSQL. - Job info (from my test box): --------------- sqoop:000> update job --jid 1 Updating job with id 1 Please update job metadata: Name: to MSworld Database configuration Schema name: dbo Table name: reg Table SQL statement: Table column names: id,name Stage table name: reg_stage Clear stage table: true Input configuration Input directory: /sqoop/reg2 --------------- Throttling resources Extractors: Loaders: Job was successfully updated with status FINE --------------------------------------------------- Thanks, Suhas.
