Ashish Thusoo commented on HADOOP-4089:
---------------------------------------

We have actually not hard coded this in the code. The scratch directory that 
the hive client side code uses is stored in the hive-default.xml and the 
hive-default.xml file contains /tmp/hive-${user.name} as the value of the 
hive.exec.scratchdir property.

This is completely modeled on how hadoop defines hadoop.tmp.dir in the 
hadoop-default.xml.



> Check if the tmp file used in the CLI exists before using it.

> Currently the CLI needs /tmp/<user-name> directory to be present, otherwise 
> it gives an error.
> We should create it automatically when we launch the CLI.
