Beeline dfs command Error: Error while processing statement: (state=,code=1)

Reproduce steps:

1. hdfs dfs -chmod 750 /tmp/aaa  (user:test)
2. beeline login with user test1
3. beeline "dfs -ls /tmp/aaa"
4. Error: Error while processing statement: (state=,code=1)

Cause:

beeline "dfs" command would call fsshell, fsshell just err.print(errmsg) and return "null" value when catching exception
