Jeff Hammerbacher commented on HIVE-969:
----------------------------------------
My question still stands. Are you planning on implementing a statistics
collection process to capture table size in the metastore for this issue?
> choose the largest table for join as the table to be streamed

> In absence of statistics, the join order is random. This creates a problem
> for the users since mostly they dont care about the size of the tables
> So, instead of choosing the join order randomly, we can make the largest
> table as the table to be streamed if the user did not specify any hints.
