Daniel Dai commented on HIVE-5510:
----------------------------------
bq. build.xml changes concurrency from 5/5 to 1/1. Why?
That's unintended. Will remove it
bq. TempletonControllerJob.Watcher.run()
bq. This also creates a JobState for each child task. What is purpose of this?
Just for each child know its parent.
bq. We never (AFAIK) get any notifications from Hadoop when a subtask
completes. When is this JobState (for child task) ever updated? If not, then
why create it? Conversely, maybe it would be useful to track the state of child
task, but I think that would require more changes like registering a callback
with JobTracker for each child task that we find. Don't know whether this is
really useful.
Only the parent field for each each child job is meaningful, we don't track
other changes for the child job
bq. DeleteDelegator
bq. it uses System.err for logging. Why not log4j which will be in webhcat.log
with WARN log level
Yes, we should, will change.
bq. JobState:
bq. getChildId() is never used
This is used by StatusDelegator. Actually getChildren is never used, but it is
there for a while, I don't want to remove it in this patch.
