Fwd: no hbase columns key in the context map

I got  "java.lang.NullPointerException" on this line in a custom serializer:
 String cols = new String(context.getString("columns"));

This is in a Serializer for HBase. I place the jar of this class in the
flume lib folder, don't know why there is no columns key in the context map?

Your suggestion or help will be appreciated!

George

Found the error, it's a typo in the configuration.
