Review request for Sqoop.
Bugs: SQOOP-2457
https://issues.apache.org/jira/browse/SQOOP-2457
Repository: sqoop-trunk
Description
-------
With CBO and different execution engines like Tez depedning on statistics like
row count heavily, it is important that we provide the option to update stats
on data loaded into Hive as part of the --hive-import option. Ideally these
should be Hive managed, but there are use cases where this is not automatic and
hence this option will help in those cases
Added a new option --hive-compute-stats which will add compute statistics
statement for the loaded table/partition as the case may be for --hive-imports
