Subject Same tablename in DESTINATION and FROM clause
Date Thu, 15 Mar 2012 11:23:55 GMT

Does the MR jobs of a hive query write directly to the destination or are the results of the
MR jobs moved to the destination at the end?
To be more precise, is it safe to write query in the following way,

insert overwrite table X
select do_something from X join Y  on (some key)

Was little reluctant to go by the experimental results and wanted to confirm.
