-------------------------------
Patch is improving.
Here's a couple of quick issues:
I created table named 'test'. I then tried to add some data:
{code}
HBase > set test values('columnfamily_name:x', 'y') where row="z";
07/06/15 16:54:24 DEBUG hbase.HClient: No servers for test. Doing a find...

Exception in thread "main" java.lang.NullPointerException
at org.apache.hadoop.hbase.shell.cmds.Set.execute(Set.java:41)
at org.apache.hadoop.hbase.shell.HBaseShell.main(HBaseShell.java:68)
{code}
If I do other than 'scan tables', it no longer throws an exception but the
message doesn't make much sense:
{code}HBase > show scan;
Missing Parameters.
{code}
Perhaps just say 'unimplemented' if its not.
Can you make it so I can scan root and meta tables?
Your patch has odd file on the end -- saveversion.sh on end -- and it was made
at /root rather than inside ${HADOOP_HOME}.
