[SPARK-7758] [SQL] Override more configs to avoid failure when connect to a postgre sql
https://issues.apache.org/jira/browse/SPARK-7758
When initializing `executionHive`, we only masks
`javax.jdo.option.ConnectionURL` to override metastore location. However,
other properties that relates to the actual Hive metastore data source are not
masked. For example, when using Spark SQL with a PostgreSQL backed Hive
metastore, `executionHive` actually tries to use settings read from
`hive-site.xml`, which talks about PostgreSQL, to connect to the temporary
Derby metastore, thus causes error.
To fix this, we need to mask all metastore data source properties.
Specifically, according to the code of [Hive `ObjectStore.getDataSourceProps()`
method] [1], all properties whose name mentions "jdo" and "datanucleus" must be
included.
[1]: https://github.com/apache/hive/blob/release-0.13.1/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L288
Have tested using postgre sql as metastore, it worked fine.
