FAQ
Hi,

I think this is a problem with open source in general and sometimes it
can be very frustrating.
However, your question is more of a "what if" question - you're not in
the trouble of finding a horrible bug after you deployed to production,
am I right?

Regarding your question, I would guess that if LOAD DATA INPATH crashes
while moving files into the Hive warehouse, the data which was moved
will appear as legitimate loaded data. Or the files will be moved but
the metadata will not be updated. In any case, you should detect the
crash and redo the operation. The easiest answer might actually be to
look into the source code - sometimes it can be easier to find than one
would expect.

Not a complete answer, but hope this helps a bit.

I submit a question like this before, but somehow that question is
never delivered. I can even find my question in google. Since I cannot
find any admin e-mail/feedback form on the hive website that I can ask
why the last question is not delivered. There is not much option other
than to post the question again and hope that the question get through
this time. Sorry for the double posting if you have seen my last e-mail.

What is the behaviour if a client of hive crashes in the middle of
running a "load data inpath" for either a local file or a file on
HDFS? Will the file be partially loaded in the db? Thanks.
