update derby.jar to eliminate the one time wait of 2-3 minutes while running junit tests
----------------------------------------------------------------------------------------
Key: HADOOP-4207
URL: https://issues.apache.org/jira/browse/HADOOP-4207
Project: Hadoop Core
Issue Type: Bug
Components: contrib/hive
Affects Versions: 0.19.0
Reporter: Prasad Chakka
Assignee: Prasad Chakka
Priority: Minor
Fix For: 0.19.0
Attachments: derby.jar
current derby.jar (version 10.4.1) has a bug where getting metadata of tables can hang upto few minutes. Hive metastore validates the existing tables & metadata while connecting and it can encounter this bug sometimes. The new version of derby.jar has a fix for this bug which would eliminate this hang.

----------------------------------------
why does hive test against derby and not hdfs; that's a lot faster at the expense of some concurrency rules; good for testing though not always what you want in production.

------------------------------------------
This is a new version of the Derby release. HadoopQA won't work here because it is not a patch file. I am running tests myself and if all goes well, will check in this patch. This files goes into src/contrib/hive/lib/derby.jar

------------------------------------------
The hive metastore code talks SQL to store the data in the db. Apache Derby is packaged into the Hadoop distribution to serve as a simple easy-to-use and lightweight SQL store. In production, people might actually use mySQL or something else instead of Derby.
