-------------------------------
Hi, [~ashutoshc]
Thank you for your suggestion, I'm afraid we can't use GenericOptionsParser in
Hive.
In hadoop, before it runs into FsShell.main(), Linux shell already parses the
parameters.
When it calls
res = ToolRunner.run(shell, argv); // " or ' already been removed from argv
For example,
[root@localhost bin]# hadoop fs -ls "ha ah"
/usr/jdk64/java-1.8.0-openjdk-1.8.0.45-28.b13.el6_6.x86_64/bin/java ...
org.apache.hadoop.fs.FsShell -ls ha ah
[root@localhost bin]# hadoop fs -ls 'a'
/usr/jdk64/java-1.8.0-openjdk-1.8.0.45-28.b13.el6_6.x86_64/bin/java ...
org.apache.hadoop.fs.FsShell -ls a
While in Hive, after launch HiveCLI, org.apache.hadoop.hive.cli.CliDriver will
handle the left inputs.
Which means that the java class in Hive should parse the input with " or ' by
itself.
That's the reason I added a customized splitCmd() method.
Thank you,
Bing

> As design, hive could support hadoop dfs command in hive shell, like
> hive> dfs -mkdir /user/biadmin/mydir;
> but has different behavior with hadoop if the path contains space and quotes
> hive> dfs -mkdir "hello";
> drwxr-xr-x - biadmin supergroup 0 2013-04-23 09:40
> /user/biadmin/"hello"
> hive> dfs -mkdir 'world';
> drwxr-xr-x - biadmin supergroup 0 2013-04-23 09:43
> /user/biadmin/'world'
> hive> dfs -mkdir "bei jing";
> drwxr-xr-x - biadmin supergroup 0 2013-04-23 09:44
> /user/biadmin/"bei
> drwxr-xr-x - biadmin supergroup 0 2013-04-23 09:44
