Review request for hive, Brock Noland, Szehon Ho, and Xuefu Zhang.
Bugs: HIVE-9877
https://issues.apache.org/jira/browse/HIVE-9877
Repository: hive-git
Description
-------
This patch is to enhance Beeline to be able to run multiple commands from a
line which is passed in via beeline console, -e or -f. In addition, it also
fixes an NPE when reading command from a file (via -f) if that line of command
is not terminated by ";"

Testing
-------
Manual tests have been done and all passed.
1. Beeline console for following commands:
a. use a ; show tables; -- beeline executes two commands and its console
displays all tables under db a
b. use a ; show tables -- beeline console prompts for more input, after typing
in ";" it executes two commands and displays tables under db a
c. use a ; show databases; show tables;" -- beeline executes all three
commands and its console displays all databases, and tables under db a
d. use a ; #show databases; show tables;" -- beeline only executes "use a"
command and skip rest cmds like "show databases" and "show tables"
2. commands passed in via -e option:
a. -e "use a ; show tables; "
b. -e "use a ; show tables" -- display tables under db a even without ; at the
end of line
c. -e "use a ; show databases; show tables" -- display all databases, and
display tables under db a
d. -e "use a ; #show databases; show tables" -- skip cmds show databases;
show tables
3. commands read from a file via -f option, file includes following commands:
{code}
show databases; #display all databases;
use a; show tables;
use a; show databases; #show tables; #do not show databases;
#do not have the ; at the end of following cmd
show databases
{code}
