Review request for hive and Zoltan Haindrich.
Bugs: HIVE-22526
https://issues.apache.org/jira/browse/HIVE-22526
Repository: hive-git
Description
-------
The Driver class contains ~600 lines of code responsible for compiling the
command. That means that from the command String a Plan needs to be created,
and also a transaction needs to be started (in most of the cases). This is a
thing done by the compile function, which has a lot of sub functions to help
this task, while itself is also really big. All these codes should be put into
a separate class, where it can do it's job without getting mixed with the other
codes in the Driver.
