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

             Summary: Provide better error message when user tries to run 
multiple IT tests
                 Key: PHOENIX-3557
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3557
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Ted Yu
            Priority: Minor


With the following command:
{code}
bin/hbase --config /etc/hbase/conf org.apache.phoenix.end2end.End2EndTestDriver 
-r *index*
{code}
I got:
{code}
Exception in thread "main" java.util.regex.PatternSyntaxException: Dangling 
meta character '*' near index 0
*index*

        at 
org.apache.phoenix.end2end.End2EndTestDriver.processOptions(End2EndTestDriver.java:114)
{code}
Error message can be refined to remind user that .\* should be used in place of 
\*

Thanks to [~elserj] for the hint.
