Description
When I run set and save command at Beeline in my environment. And NullPointerException occurred as follows.
[root@hive ~]# /usr/local/hive/bin/beeline Beeline version 2.0.0-SNAPSHOT by Apache Hive beeline> !set java.lang.NullPointerException beeline> !save Saving preferences to: /root/.beeline/beeline.properties java.lang.NullPointerException
This problem has occurred because the following method's return value in BeeLineOpts#toProperties is null.
beeLine.getReflector().invoke(this, "get" + names[i], new Object[0]).toString()
Therefore it is modified so as to avoid NullPointerException.
