dhruba borthakur commented on HADOOP-4207:
------------------------------------------

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

> 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.
