Subject Exception after upgrading to 0.20.2
Date Wed, 02 Dec 2009 18:09:52 GMT
Hello,

After upgrading HBase from 0.20.0 to 0.20.2 I am getting following error
message:

java.lang.reflect.UndeclaredThrowableException

This is happening for the following line in my code:

this.table = new HTable(new HBaseConfiguration(), tableName);

This used to work flawlessly before, so seems like something changed in
HBaseConfiguration, may be?  I am looking into this, but any pointers would
be greatly appreciated.


Thanks.
