Description

When performing append operation on non-existing column families, NullPointerException is thrown in hbase shell as shown below:

hbase(main):007:0> append 't1', 'r1', 'none:c1', '123'

This seems to be caused by absence of check for valid family names as done in other operations like 'Put' in HRegion.java
