Artem Aliev created SPARK-11208:
-----------------------------------
Summary: Filter out 'hive.metastore.rawstore.impl' from
executionHive temporary config
Key: SPARK-11208
URL: https://issues.apache.org/jira/browse/SPARK-11208
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.1, 1.6.0
Reporter: Artem Aliev
Spark use two hive meta stores: external one for storing tables and internal
one (executionHive):
{code}
/**
The copy of the hive client that is used for execution. Currently this must
always be
Hive 13 as this is the version of Hive that is packaged with Spark SQL. This
copy of the
client is used for execution related tasks like registering temporary functions
or ensuring
that the ThreadLocal SessionState is correctly populated. This copy of Hive is
not used
for storing persistent metadata, and only point to a dummy metastore in a
temporary directory. */
{code}
The executionHive assumed to be a standard meta store located in temporary
directory as a derby db. But hive.metastore.rawstore.impl was not filtered out
so any custom implementation of the metastore with other storage properties
(not JDO) will persist that temporary functions. CassandraMetaStore from
DataStax Enterprise is one of examples.
