Sahil Takiar commented on HIVE-14535:
-------------------------------------
Thanks a ton [~gopalv]! Definitely helps a lot, don't want to go down the
direct write approach if we have already seen users hit issues with it. Could
you expand a little more on your comment about writing to the same file name?
Was Hive modified to force each task attempt to write to the same file? In that
case what was the exact issue with checksum-safety? Was one of the writes
rejected?
Also, want to understand more how it can lead to data loss? Wouldn't the query
fail if something like this happens?
> add micromanaged tables to Hive (metastore keeps track of the files)
