[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
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)
