Namit Jain commented on HIVE-4106:
----------------------------------
The last query is wrong:
explain select count(*) FROM bucket_small a JOIN bucket_medium b ON a.key =
b.key JOIN bucket_big c ON c.key = b.key JOIN bucket_medium d ON c.key = b.key;
Most probably, the intention was:
explain select count(*) FROM bucket_small a JOIN bucket_medium b ON a.key =
b.key JOIN bucket_big c ON c.key = b.key JOIN bucket_medium d ON c.key = d.key;
Having said that, it should not die.
