Steve Loughran created HIVE-12928:
-------------------------------------
Summary: SessionState.start() to include filename in failures to
set up temp paths
Key: HIVE-12928
URL: https://issues.apache.org/jira/browse/HIVE-12928
Project: Hive
Issue Type: Improvement
Affects Versions: 1.2.1
Environment: Test system where java.io.tmpdir wasn't writeable by user
Reporter: Steve Loughran
When hive can't write to the tmpdir you get —as you'd expect— a stack trace.
unfortunately, what you get is a multiple-wrapped stack trace without any
details as to what went wrong:
{code}
java.lang.RuntimeException: java.lang.RuntimeException: java.io.IOException:
Permission denied
{code}
This makes finding the root cause somewhat harder than necessary.
It seems to me that
# Any IOE raised on failure to create a temp file should be caught and rethrown.
# there's no need to wrap a {{RuntimeException}} with a {{RuntimeException}.
I can do a patch for this, if people promise to review it and then, perhaps,
even commit it.
