ColumnAggregationEndPoint- Causes null pointer in RS when we pass null column
qualifier
---------------------------------------------------------------------------------------
Key: HBASE-5082
URL: https://issues.apache.org/jira/browse/HBASE-5082
Project: HBase
Issue Type: Bug
Reporter: ramkrishna.s.vasudevan
Priority: Minor
I was trying to use the ColumnAggregationEndPoint.sum().
In my sample is just created a column family but did not use any qualifier and
inserted some data.
I tried to use ColumnAggregationEndPoint.sum(qualifier, null). When i did
this inside the ColumnAggregationEndPoint we do
scan.addColumn(). This is adding the [null] array in the scan object. Later
in the scanQueryMatcher it is throwing nullpointer exception.
I can understand that addColumn() is to specifiy the qualifier.
Do we need to document somewhere saying qualifier should not be null? I think
coprocessors can be used even in places where we don't have qualifiers. If that
is the case this sample ColumnAggregationEndPoint may not work.
