[jira] [Commented] (CRUNCH-216) Transpose arguments in MapsideJoinStrategy.join

    [ https://issues.apache.org/jira/browse/CRUNCH-216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13743381#comment-13743381 ] 

Micah Whitacre commented on CRUNCH-216:
---------------------------------------

Did we miss getting this issue resolved in the 0.7.0?

Since this is now released as part, I'm not sure that a javadoc is sufficient for such a non-passive change.

> The MapsideJoinStrategy currently specifies that the smaller table in the join (i.e. the table to be replicated and loaded in memory) should be on the right-hand side of the join.
> This is the opposite of what is done in all other join strategies, making it impossible to just switch out another join strategy for a MapsideJoinStrategy. The MapsideJoinStrategy could be brought in line with the other JoinStrategies to expect the smaller of two tables to be provided as the left-side table.
