1. Is there a way to check the size of the hash table created during map side join in Hive/Tez? 2. Is the hash table (small table's), created for the entire table or only for the selected and join key columns? 3. The hash table (created in map side join) spills to disk, if it does not fit in memory Is there a parameter in hive/tez to specify the percentage of the hash file which can spill?
Thanks!
