Kousuke Saruta updated SPARK-2970:
----------------------------------
Description:
When spark-sql script run with spark.eventLog.enabled set true, it ends with
IOException because FileLogger can not create APPLICATION_COMPLETE file in HDFS.
It's is because a shutdown hook of SparkSQLCLIDriver is executed after a
shutdown hook of org.apache.hadoop.fs.FileSystem is executed.
When spark.eventLog.enabled is true, the hook of SparkSQLCLIDriver finally try
to create a file to mark the application finished but the hook of FileSystem
try to close FileSystem.
was:
When spark-sql script run with spark.eventLog.enabled set true, it ends with
IOException because FileLogger can not create APPLICATION_COMPLETE file in HDFS.
I think it's because FIleSystem is closed by HiveSessionImplWithUGI.
It has a code as follows.
{code}
public void close() throws HiveSQLException {
try {
acquire();
ShimLoader.getHadoopShims().closeAllForUGI(sessionUgi);
cancelDelegationToken();
} finally {
release();
super.close();
}
}
{code}
When using Hadoop 2.0+, ShimLoader.getHadoopShim above returns Hadoop23Shim
which extends HadoopShimSecure.
HadoopShimSecure#closeAllForUGI is implemented as follows.
{code}
@Override
public void closeAllForUGI(UserGroupInformation ugi) {
try {
FileSystem.closeAllForUGI(ugi);
} catch (IOException e) {
LOG.error("Could not clean up file-system handles for UGI: " + ugi, e);
}
}
{code}
