--------------------------------------
Hi Namit,
The test case is not from our set of files/tables/TestCliDriver tests. I had to
get lucky to catch this issue. The issue can be reproduced if we have a
partitioned table with average size being in some range so that
getBigTablePosition in the AvgPartitionSizeBasedBigTableSelectorForAutoSMJ
returns a position not in the joinContext. This will cause the exception. In my
setup, I got lucky to have such a partition combination. I am not sure how I
can reproduce this issue with our current partitioned tables set in the
TestCliDriver. I will try it with some combinations to see if it can be
produced.
If we say this type of join has to be rejected, we will not convert this join
to an SMB Map-join even if it is possible right? That seems extreme. Also, I do
not see any references to setRejectedJoinOps in the code either. Please let me
know.
Thanks
Vikram.
