Jim Kellerman commented on HADOOP-1341:
---------------------------------------
HBase does not access any of the .xml files directly. It uses a Configuration
object which in the test environment grabs the settings out of src//.xml
The only reason I asked was that there was previously an issue where tests were
timed out if they ran longer than a setting in the configuration. Later, that
setting was removed from the xml file, but if it was set and the test killed in
the middle, I can envision all kinds of errors emerging.
That not being the case, I'll see if I can figure out how this is happening.
If you could upload a portion of your log file while that test is running that
would be helpful in determining what part of the test this is happening in.
