Edward J. Yoon commented on HAMA-89:
------------------------------------
Here's few comments
- There is a typing error. 'HBase Shell' should be 'Hama Shell'
- Let's hide a ParseException error message for easy-to-read using try/catch.
----
Hama > asdfsd
org.apache.hama.shell.parser.script.ParseException: Encountered "asdfsd" at
line 2, column 1.
Was expecting one of:
<EOF>
"help" ...
"quit" ...
"" ...
<EOL> ...
HAMA V1.0 SHELL COMMANDS
all the supported commands in hama shell will be:
'<hama expression> ;',
'quit',
'help'.
Try type 'help' to see details.

> It would be nice if shell shows simple guide instead of error message.
