----------------------------------------
Summary: Use murmur hash to create bucketed tables
Key: HIVE-7148
URL: https://issues.apache.org/jira/browse/HIVE-7148
Project: Hive
Issue Type: Bug
Reporter: Gunther Hagleitner
HIVE-7121 introduced murmur hashing for queries that don't insert into bucketed
tables. This was done to achieve better distribution of the data. The same
should be done for bucketed tables as well, but this involves making sure we
don't break backwards compat. This probably means that we have to store the
partitioning function used in the metadata and use that to determine if SMB and
bucketed map-join optimizations apply.
