Subject [jira] Updated: (HIVE-1226) support filter pushdown against non-native tables
Date Fri, 10 Sep 2010 21:56:34 GMT

John Sichi updated HIVE-1226:
-----------------------------

    Attachment: HIVE-1226.2.patch

Almost there...but just realized that I haven't included the predicate analysis in getSplits,
and we need it there (e.g. in the HBase case to avoid generating splits for regions which
can't possibly contain the key).  So one more patch coming after this and then it's ready
for review.
