> I created a model with no partition column specified, step "Extract Fact
> Table Distinct Columns" failed with MR log
> "org.apache.hadoop.mapred.YarnChild: Exception running child :
> java.lang.NullPointerException at
> org.apache.kylin.cube.model.CubeJoinedFlatTableDesc.getColumnIndex(CubeJoinedFlatTableDesc.java:145)".
> I doubt the root cause is in
> org.apache.kylin.cube.CubeManager#getAllDictColumnsOnFact, a null value is
> added to the return list due to
> cubeDesc.getModel().getPartitionDesc().getPartitionDateColumnRef() gets null.
> Attached is the patch to fix, only add a null check.
