Description

Here is a list of failed tests: Join_6, MergeJoin_5, Join_8, Join_7, MergeJoin_2, MergeJoin_3, MergeJoin_8, MergeJoin_1, MultiQuery_14, MergeJoin_4, MergeJoin_9, MergeJoin_6, MergeJoin_7.

In these tests, Pig need to read a local file distributed by distribute cache. However, Pig try to read hdfs instead. Here is the stack:
