There are a few known limitations, all of which can be handled in trunk as far as I can tell (i.e.: None of them are large disruptive changes that still require a branch.) > Limitations: > - Union all is not yet supported on Tez > - SMB is not yet supported on Tez > - Bucketed map-join is executed as broadcast join (bucketing is ignored) > Since the user is free to toggle hive.optimize.tez, it's obviously possible to just run these on MR. > I am hoping to follow the approach that was taken with vectorization and shoot for a merge instead of single commit. This would retain history of the branch. Also in vectorization we required at least three +1s before merge, I'm hoping to go with that as well. > I will add a combined patch to this ticket for review purposes (not for commit). I'll also attach instructions to run on a cluster if anyone wants to try. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
