streamline metastore options in hive-default.xml
------------------------------------------------
Key: HADOOP-4580
URL: https://issues.apache.org/jira/browse/HADOOP-4580
Project: Hadoop Core
Issue Type: Improvement
Components: contrib/hive
Affects Versions: 0.19.0
Reporter: Prasad Chakka
Priority: Minor
there are quite a few metastore configurations for hive.
1) specify the type of metastore to use (sql or file -- usefilestore option)
2) embedded derby datbase (by setting JDBCDriverName option)
3) local mode (where each instance of hive connects to the sql store directly
-- local option)
4) remote mode (where each instance of hive connects to a metastore server
instead of sql store (using uri option)
names and setting all these options are very confusing and not simple. This
JIRA is to streamline this to make these options more simple.
