Jim Kellerman updated HADOOP-2324:
----------------------------------
Priority: Minor (was: Major)
The test timing out because something does not shut down cleanly should be
fixed by HADOOP-2338
I have not seen an assertion failure for some time in either patch or nightly
builds.
The latest nightly build failure (build #325) failed because the client ran out
of retries. This can probably be fixed by tweaking some config parameters.
Downgrading priority to minor, because it is annoying, but should be easy to
fix if it should occur again.
> [hbase] Fix assertion failures in TestTableMapReduce
> ----------------------------------------------------
>
> Key: HADOOP-2324
> URL: https://issues.apache.org/jira/browse/HADOOP-2324
> Project: Hadoop
> Issue Type: Bug
> Components: contrib/hbase
> Affects Versions: 0.16.0
> Reporter: Jim Kellerman
> Assignee: Jim Kellerman
> Priority: Minor
> Fix For: 0.16.0
>
>
> TestTableMapReduce consists of two tests: a very simple one that verifies
> that it is working, and a larger test that verifies that it works when the
> table consists of multiple regions.
> There are two failure modes:
> 1) an assertion failure in the verify method
> 2) the test times out because something does not shut down cleanly.
> to figure out what is causing these failures, the first step will be to do
> copious logging in the test. Once the root cause is determined, we can
> address it.
> Unfortunately, some of the testing will have to be done via Hudson, because
> that is the only environment in which it fails. We routinely test under
> Windows, Fedora Core 6, MacOsX, and Ubuntu. Windows and Ubuntu have both
> single and dual processor configurations. FC6 and MacOS run on dual core
> machines.
> Only Hudson seems crippled enough to demonstrate these problems. (A good
> thing since they are real problems)
