Description

Env: hive master
Steps to reproduce:

1. clear previous beeline.properties (rm -rf ~/.beeline/beeline.properties)

2. Launch beeline, "!save" and exit. This would create new "~/.beeline/beeline.properties", which would have "beeline.hiveconfvariables={}"

3. Launch "beeline --hiveconf hive.tmp.dir=/tmp". This would throw NPE
