dhruba borthakur commented on HADOOP-3245:
------------------------------------------
I think you would not lose any data (even if small). 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.
> Provide ability to persist running jobs (extend HADOOP-1876)
