Karthik Kambatla updated MAPREDUCE-4629:
----------------------------------------
Description:
Remove JobHistory.DEBUG_MODE for the following reasons:
1. No one seems to be using it - the config parameter corresponding to enabling
it does not even exist in mapred-default.xml
2. The logging being done in DEBUG_MODE needs to move to LOG.debug() and
LOG.trace()
3. Buggy handling of helper methods in DEBUG_MODE; e.g. directoryTime() and
timestampDirectoryComponent().
was:
The helper methods in JobHistory - directoryTime() and
timestampDirectoryComponent() - adjust the month field for readability (Jan is
0 as per Calendar, 1 for us)
In DEBUG_MODE, JobHistory uses hour instead of month. However, the adjustment
is still applied.
Affects Version/s: 2.0.0-alpha
Hadoop Flags: Incompatible change
Summary: Remove JobHistory.DEBUG_MODE (was: In DEBUG_MODE,
JobHistory#directoryTime() returns incorrect time)
