Description

Reference : https://github.com/cloudera/Impala/blob/f2d414093df3f5c1b65512fa82682308ae33edb2/shell/impala-shell#L40

This line in impala-shell sets python egg cache to /tmp path.

PYTHON_EGG_CACHE=/tmp/impala-shell-python-egg-cache-${USER}

Not all users want to give exec permission on /tmp directory for security reasons.
Hence, please make this configurable.
