Amar Kamat commented on HADOOP-3245:
------------------------------------
bq. If you have done a sync after a write to a HDFS file and then do not do
anything else to that file for 1 hour the namenode will recover that file and
will make all the data that was synced earlier to appear in the file.
Is this time (1hr) configurable? Can it be configured on per file basis?
> Provide ability to persist running jobs (extend HADOOP-1876)

> applied for things like jobs being able to survive jobtracker restarts.
