Hi All, I'm working on Hadoop CDH3 U0 and Sqoop CDH3 U2.
I'm trying to export csv files from HDFS to Teradata, it works well with setting mapper to "1" ( with batch loading of 1000 records at a time ). when I tried increasing the number of mappers to more than one I'm getting the following error. Also, is it possible to configure batch size at the time of export? sqoop export --verbose --driver com.teradata.jdbc.TeraDriver --connect jdbc:teradata://xxxx/database=xxxx --username xxxxx --password xxxxx --table xxxx --export-dir /user/surasani/10minutes.txt --fields-terminated-by '|' -m 4 --batch 12/01/24 16:17:21 INFO mapred.JobClient: map 3% reduce 0% 12/01/24 16:17:48 INFO mapred.JobClient: Task Id : attempt_201112211106_68553_m_000001_2, Status : FAILED *java.io.IOException: java.sql.BatchUpdateException: [Teradata Database] [TeraJDBC 13.00.00.07] [Error 2631] [SQLState 40001] Transaction ABORTed due to DeadLock*. at com.cloudera.sqoop.mapreduce.AsyncSqlRecordWriter.write(AsyncSqlRecordWriter.java:223) at com.cloudera.sqoop.mapreduce.AsyncSqlRecordWriter.write(AsyncSqlRecordWriter.java:49) at org.apache.hadoop.mapred.MapTask$NewDirectOutputCollector.write(MapTask.java:530) at org.apache.hadoop.mapreduce.TaskInputOutputContext.write(TaskInputOutputContext.java:80) at com.cloudera.sqoop.mapreduce.TextExportMapper.map(TextExportMapper.java:82) at com.cloudera.sqoop.mapreduce.TextExportMapper.map(TextExportMapper.java:40) at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:144) at com.cloudera.sqoop.mapreduce.AutoProgressMapper.run(AutoProgressMapper.java:189) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:646) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:322) at org.apache.hadoop.mapred.Child$4.run(Child.java:268) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:396) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1115) at org.apache.hadoop.mapred.Child.main(Child.java:262) Caused by: java.sql.BatchUpdateException: [Teradata Database] [TeraJDBC 13.00.00.07] [Error 2631] [SQLState 40001] Transaction ABORTed due to DeadLock. at com.teradata.jdbc.jdbc_4.util.ErrorFactory.convertToBatchUpdateException(ErrorFactory.java:116) at com.teradata.jdbc.jdbc_4.PreparedStatement.executeBatchDMLArray(PreparedStatement.java:149) at com.teradata.jdbc.jdbc_3.ifjdbc_4.TeraLocalPreparedStatement.executeBatch(TeraLocalPreparedStatement.java:299) at com.cloudera.sqoop.mapreduce.AsyncSqlOutputFormat$AsyncSqlExecThread.run(AsyncSqlOutputFormat.java:232) Caused by: com.teradata.jdbc.jdbc_4.util.JDBCException: [Teradata Database] [TeraJDBC 13.00.00.07] [Error 2631] [SQLState 40001] Transaction ABORTed due to DeadLock. at com.teradata.jdbc.jdbc_4.util.ErrorFactory.makeDatabaseSQLException(ErrorFactory.java:288) at com.teradata.jdbc.jdbc_4.statemachine.ReceiveInitSubState.action(ReceiveInitSubState.java:102) at com.teradata.jdbc.jdbc_4.statemachine.StatementReceiveState.subStateMachine(StatementReceiveState.java:285) at com.teradata.jdbc.jdbc_4.statemachine.StatementReceiveState.action(StatementReceiveState.java:176) at com.teradata.jdbc.jdbc_4.statemachine.StatementController.runBody(StatementController.java:108) at com.teradata.jdbc.jdbc_4.statemachine.PreparedBatchStatementController.run(PreparedBatchStatementController.java:59) at com.teradata.jdbc.jdbc_4.Statement.executeStatement(Statement.java:331) at com.teradata.jdbc.jdbc_4.PreparedStatement.executeBatchDMLArray(PreparedStatement.java:138) ... 2 more 12/01/24 16:17:49 INFO mapred.JobClient: map 4% reduce 0% 12/01/24 16:17:52 INFO mapred.JobClient: map 5% reduce 0% 12/01/24 16:21:16 INFO mapred.JobClient: Job complete: job_201112211106_68553 12/01/24 16:21:16 INFO mapred.JobClient: Counters: 8 12/01/24 16:21:16 INFO mapred.JobClient: Job Counters 12/01/24 16:21:16 INFO mapred.JobClient: SLOTS_MILLIS_MAPS=1709245 12/01/24 16:21:16 INFO mapred.JobClient: Total time spent by all reduces waiting after reserving slots (ms)=0 12/01/24 16:21:16 INFO mapred.JobClient: Total time spent by all maps waiting after reserving slots (ms)=0 12/01/24 16:21:16 INFO mapred.JobClient: Rack-local map tasks=1 12/01/24 16:21:16 INFO mapred.JobClient: Launched map tasks=6 12/01/24 16:21:16 INFO mapred.JobClient: Data-local map tasks=3 12/01/24 16:21:16 INFO mapred.JobClient: SLOTS_MILLIS_REDUCES=0 12/01/24 16:21:16 INFO mapred.JobClient: Failed map tasks=1 12/01/24 16:21:16 INFO mapreduce.ExportJobBase: Transferred 0 bytes in 862.1506 seconds (0 bytes/sec) 12/01/24 16:21:16 INFO mapreduce.ExportJobBase: Exported 0 records. 12/01/24 16:21:16 ERROR tool.ExportTool: Error during export: Export job failed!
