Venkat Ranganathan commented on HIVE-8646:
------------------------------------------
bq. How come this class isn't present? Are you not adding hive-metastore to
the required jars?
Hive-metastore is always packaged as part of the oozie hive sharelib. This
issue is seen intermittently. This could be related to localization of jars,
the claaspath jar or some thing within hive that triggers an indeterminate
class loading order. That said, [~rhbutani], [~ashutoshc] also looked into
this and think that this exception block is not needed and can/need to be
removed since the introduction of the new serialization facility used.

> Key: HIVE-8646
> URL: https://issues.apache.org/jira/browse/HIVE-8646
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.14.0
> Environment: Hadoop 2.6.0 + Hive 0.14 + Oozie 4.1
> Reporter: Venkat Ranganathan
>
> When running Hive actions with Oozie we hit this issue sometimes. What is
> interesting is that we have all the necessary jars in the classpath (or
> atleast are expected to be localized).
> This static initialization block is introduced by HIVE-3925.
