-----------------------------------------------
@Ted
Patch is good.
I have a suggestion, from the logs could see that the NameSpaceJanitor issues a
scan on the Meta and that includes Namespace into the blockcache summary.
>From code am not getting where the scan is happening through NameSpaceJanitor.

May be instead working with the index, we can just check if the testTable and
testTable2 are available in the list that we are checking.
If the catalog janitor adds any other namespace entries this may fail? So we
will check if the list contains those two tables then it may be easier.
