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

             Summary: commands.rb is giving wrong error messages on exceptions
                 Key: HBASE-10533
                 URL: https://issues.apache.org/jira/browse/HBASE-10533
             Project: HBase
          Issue Type: Bug
          Components: shell
            Reporter: rajeshbabu
            Assignee: rajeshbabu
             Fix For: 0.96.2, 0.98.1, 0.99.0, 0.94.17


1) Clone into existing table name is printing snapshot name instead of table name.
{code}
hbase(main):004:0> clone_snapshot 'myTableSnapshot-122112','table'

ERROR: Table already exists: myTableSnapshot-122112!
{code}
The reason for this is we are printing first argument instead of exception message.
{code}
        if cause.kind_of?(org.apache.hadoop.hbase.TableExistsException) then
          raise "Table already exists: #{args.first}!"
        end
{code}
2) If we give wrong column family in put or delete. Expectation is to print actual column families in the table but instead throwing the exception.
{code}
hbase(main):002:0> put 't1','r','unkwown_cf','value'

        at java.lang.Thread.run(Thread.java:662)
: 1 time,

{code}

The reason for this is server will not throw NoSuchColumnFamilyException directly, instead RetriesExhaustedWithDetailsException will be thrown.
