Rui Li commented on HIVE-8991:
------------------------------
I looked a little more into this. It seems hive-exec is properly added to class
path (as user application jar in {{SparkSubmit}}) and class loader can load
{{HiveIgnoreKeyTextOutputFormat}}:
{noformat}
2014-12-04 08:35:33,383 INFO [stdout-redir-1]: client.SparkClientImpl
(SparkClientImpl.java:run(384)) - [Loaded
org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat from
file:/home/hive/packaging/target/apache-hive-0.15.0-SNAPSHOT-bin/apache-hive-0.15.0-SNAPSHOT-bin/lib/hive-exec-0.15.0-SNAPSHOT.jar]
{noformat}
Nevertheless I still get the following error:
{noformat}
2014-12-04 08:32:26,681 INFO [stderr-redir-1]: client.SparkClientImpl
(SparkClientImpl.java:run(384)) - java.lang.NoClassDefFoundError:
org/apache/hadoop/hive/ql/io/HiveIgnoreKeyTextOutputFormat
{noformat}
Besides, the exception is thrown when we try to deserialize SparkWork in the
job, which means {{org.apache.hadoop.hive.ql.exec.spark.KryoSerializer}} has
been loaded properly.
I'll do more debugging. Wondering if it's possible the error message is not
accurate.
As for {{SparkSubmitDriverBootstrapper}} hanging issue, it's because it calls
System.exit in a shutdown hook which causes deadlock. It's been fixed in latest
branch.
