> Hit this problem in our internal staging cluster. Not sure why, but probably,
> there was a partial successful 'alter table' call that removed a family. As
> it is 'partial successful', there are still some stale store files of the
> removed family left under the region directory. And in
> SplitTableRegionProcedure and MergeTableRegionsProcedure, we will get all the
> store files by listing the file system, so we will also get the stale store
> files for the family which should have been removed already, and then causes
> NPE when we want to access the ColumnFamilyDescriptor.
> Although it is not the common case that there are store files for removed
> families, but FWIW, I think we can do something to make our procedures more
> robust...
