[jira] [Created] (HBASE-4325) Improve error message when using STARTROW for meta scans.

Improve error message when using STARTROW for meta scans.
---------------------------------------------------------

                 Key: HBASE-4325
                 URL: https://issues.apache.org/jira/browse/HBASE-4325
             Project: HBase
          Issue Type: Bug
            Reporter: Jonathan Hsieh
             Fix For: 0.90.4


While in shell, when doing one of these:
{code}
get '.META.','table,d110818d237e63f-b236-4c89-a2c7-5f6342110818'
scan '.META.', {LIMIT => 10 , STARTROW=>'table,d110818d3f72650-4a61-4352-ab49-707b42110818'}
{code}

The call fails with a cryptic message:

{code}
ERROR: org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact region server hp-node02.phx1.mozilla.com:60020 for region .META.,,1, row 'crash_reports,d110818d237e63f-b236-4c89-a2c7-5f6342110818', but failed after 7 attempts.

{code}

Apparently the solution is to have the proper number of commas in the query.  

{code}
get '.META.','table,d110818d237e63f-b236-4c89-a2c7-5f6342110818,'
scan '.META.', {LIMIT => 10 , STARTROW=>'table,d110818d3f72650-4a61-4352-ab49-707b42110818,'}
{code}

A better actionable error message should be reported.
