Subject [jira] Updated: (HIVE-1019) java.io.FileNotFoundException: HIVE_PLAN (No such file or directory)

Ning Zhang updated HIVE-1019:

    Attachment: HIVE-1019-8.patch

The changes look fine in general. However, I found a new issue related to this JIRA. I'm uploading
a new patch HIVE-1019-8.patch to include the fix as well.

Basically the issue is that when we set hive.exec.parallel=true and two parallel jobs are
reading the PLAN for the same file. This is an existing issue and it exists when applying
to your patch. The reason is that the session ID (which now used as the Plan file suffix)
is not changed for different session. We need to generate a new session ID for each started
session in the parallel execution case. A unit test is also added to reproduce the issue in
the current trunk.

Bennie, is it possible to add a new unit test for the case you are solving?
