Description

we found that user can not get exported environment variables in Hive beeline.

how to reproduce:
1. start hiveserver2 service
2. beeline embedded mode:
[root@bdw-master hive232]# export AAA=aaa
[root@bdw-master ~]# echo $HADOOP_HOME
/opt/hive_package/hadoop273
[root@bdw-master hive232]# bin/beeline -u 'jdbc:hive2://localhost:10000' -n root -p 123456
0: jdbc:hive2://localhost:10000> set env:AAA;
Error: Error while processing statement: null (state=,code=1)

but we found that we can get HADOOP_HOME JAVA_HOME etc. variables:

0: jdbc:hive2://localhost:10000> set env:HADOOP_HOME;
--------------------------------------------------

set

--------------------------------------------------

env:HADOOP_HOME=/opt/hive_package/hadoop273

--------------------------------------------------
1 row selected (0.097 seconds)

0: jdbc:hive2://localhost:10000> set env:JAVA_HOME;
---------------------------------------

set

---------------------------------------

env:JAVA_HOME=/usr/java/jdk1.8.0_131

---------------------------------------
1 row selected (0.09 seconds)
