  • When using the default Sqoop connector for Oracle, some data does get transferred, but during the map-reduce job, seeing lots of errors as below: attempt_201105261333_0002_m_000001_0: log4j:WARN Not allowed to write to a closed appender. 11/05/26 16:23:47 INFO mapred.JobClient: Task Id : attempt_201105261333_0002_m_000002_0, Status : FAILED java.lang.RuntimeException: java.lang.RuntimeException: java.sql.SQLRecoverableException: IO Error: Connection reset at com.cloudera.sqoop.mapreduce.db.DBInputFormat.setConf(DBInputFormat.java:164) at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:62) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:117) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:605) 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.lang.RuntimeException: java.sql.SQLRecoverableException: IO Error: Connection reset at com.cloudera.sqoop.mapreduce.db.DBInputFormat.getConnection(DBInputFormat.java:190) at com.cloudera.sqoop.mapreduce.db.DBInputFormat.setConf(DBInputFormat.java:159) ... 9 more Caused by: java.sql.SQLRecoverableException: IO Error: Connection reset at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:428) at oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:536) at oracle.jdbc.driver.T4CConnection.<init>(T4CConnection.java:228) at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:32) at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:521) at java.sql.DriverManager.getConnection(DriverManager.java:582) at java.sql.DriverManager.getConnection(DriverManager.java:185) at com.cloudera.sqoop.mapreduce.db.DBConfiguration.getConnection(DBConfiguration.java:152) at com.cloudera.sqoop.mapreduce.db.DBInputFormat.getConnection(DBInputFormat.java:184) ... 10 more Caused by: java.net.SocketException: Connection reset at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:96) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at oracle.net.ns.DataPacket.send(DataPacket.java:199) at oracle.net.ns.NetOutputStream.flush(NetOutputStream.java:211) at oracle.net.ns.NetInputStream.getNextPacket(NetInputStream.java:227) at oracle.net.ns.NetInputStream.read(NetInputStream.java:175) at oracle.net.ns.NetInputStream.read(NetInputStream.java:100) at oracle.net.ns.NetInputStream.read(NetInputStream.java:85) at oracle.jdbc.driver.T4CSocketInputStreamWrapper.readNextPacket(T4CSocketInputStreamWrapper.java:123) at oracle.jdbc.driver.T4CSocketInputStreamWrapper.read(T4CSocketInputStreamWrapper.java:79) at oracle.jdbc.driver.T4CMAREngine.unmarshalUB1(T4CMAREngine.java:1122) at oracle.jdbc.driver.T4CMAREngine.unmarshalSB1(T4CMAREngine.java:1099) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:288) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:191) at oracle.jdbc.driver.T4CTTIoauthenticate.doOAUTH(T4CTTIoauthenticate.java:366) at oracle.jdbc.driver.T4CTTIoauthenticate.doOAUTH(T4CTTIoauthenticate.java:752) at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:366) ... 18 more At the end: 11/05/26 16:27:51 INFO mapred.JobClient: Job complete: job_201105261333_0002 11/05/26 16:27:51 INFO mapred.JobClient: Counters: 13 11/05/26 16:27:51 INFO mapred.JobClient: Job Counters 11/05/26 16:27:51 INFO mapred.JobClient: SLOTS_MILLIS_MAPS=790364 11/05/26 16:27:51 INFO mapred.JobClient: Total time spent by all reduces waiting after reserving slots (ms)=0 11/05/26 16:27:51 INFO mapred.JobClient: Total time spent by all maps waiting after reserving slots (ms)=0 11/05/26 16:27:51 INFO mapred.JobClient: Launched map tasks=10 11/05/26 16:27:51 INFO mapred.JobClient: SLOTS_MILLIS_REDUCES=0 11/05/26 16:27:51 INFO mapred.JobClient: Failed map tasks=1 11/05/26 16:27:51 INFO mapred.JobClient: FileSystemCounters 11/05/26 16:27:51 INFO mapred.JobClient: HDFS_BYTES_READ=222 11/05/26 16:27:51 INFO mapred.JobClient: FILE_BYTES_WRITTEN=108922 11/05/26 16:27:51 INFO mapred.JobClient: HDFS_BYTES_WRITTEN=462 11/05/26 16:27:51 INFO mapred.JobClient: Map-Reduce Framework 11/05/26 16:27:51 INFO mapred.JobClient: Map input records=8 11/05/26 16:27:51 INFO mapred.JobClient: Spilled Records=0 11/05/26 16:27:51 INFO mapred.JobClient: Map output records=8 11/05/26 16:27:51 INFO mapred.JobClient: SPLIT_RAW_BYTES=222 11/05/26 16:27:51 INFO mapreduce.ImportJobBase: Transferred 462 bytes in 379.7796 seconds (1.2165 bytes/sec) 11/05/26 16:27:51 INFO mapreduce.ImportJobBase: Retrieved 8 records. 11/05/26 16:27:51 ERROR tool.ImportTool: Error during import: Import job failed! As Paul Socha pointed out, the workaround is to change the setup for your application, by adding this parameter to the java command: -Djava.security.egd=file:/dev/../dev/urandom This should be documented in the Sqoop User Guide.
