Amar Kamat commented on HADOOP-5921:
------------------------------------
Steve/Devaraj, as of today the jobtracker simply busy-waits for the namenode to
be up. I simply added one more busy wait for the namenode to be ready (for file
creations). This is marked as a bug fix and hence I propose to keep it as it is
and track the refactoring in some other enhancement jira. Refactoring
JobTracker's constructor requires considerable effort. Comments?
