Enis Soztutar commented on HADOOP-4209:
---------------------------------------
Both of the proposals change the attemptid format, although the first one is
implicit. But I am not sure if we want to put 2 different integers in one
field, instead of keeping them separate.
The format is very similar to the current one, except timestamp is an
incrementing int, and attempt id and timestamp places switched.
The initial reason we have introduced job, task, attempt ids is that folks
should not in any case parse the strings, and we can make changes to the format
w/o breaking compatibility. However if you are concerned about compatibility
then we should go with Owen's suggestion.
> The TaskAttemptID should not have the JobTracker start time

> The TaskAttemptID now includes the redundant copy of the JobTracker's start
> time as milliseconds. We should instead change the JobID to have the longer
> unique string.
