Description

The HBase API docs says when the row does not exist, getRow() returns

RowResult is empty if row does not exist.

However, in regionserver/HRegionServer.java's getRow():

if (result == null || result.isEmpty())
return null;
return new RowResult(row, result);

It actually returns null. Either fix the code or the document.
