Arvind Das commented on HADOOP-7911:
------------------------------------

Hii Todd, I did not know. But if you say...that could really be a problem of configuration.
Sorry, If I wasted your time. And If you have any good reference of connecting a grails app
to hadoop...please tell me.
Thanks :)

> Hii there, I am new to hadoop and I was trying to connect it to my grails application.
I tested it with java program and it worked successfully. Then I moved on for grails app.
Configuring mysql is easy and I can easily connect with it. But when I tried to connect via
grails app....

> gorm-hbase plugin installed.
> My master server was running successfully. But its port number is different and changes
if I restart hbase. (think I have done some novice mistake) Please help me out
