--------------------------------------
Summary: metastore JDO filter pushdown for integers may produce
unexpected results with non-normalized integer columns
Key: HIVE-6052
URL: https://issues.apache.org/jira/browse/HIVE-6052
Project: Hive
Issue Type: Bug
Affects Versions: 0.12.0, 0.13.0
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
If integer partition columns have values stores in non-canonical form, for
example with leading zeroes, the integer filter doesn't work. That is because
JDO pushdown uses substrings to compare for equality, and SQL pushdown is
intentionally crippled to do the same to produce same results.
Probably, since both SQL pushdown and integers pushdown are just perf
optimizations, we can remove it for JDO (or make configurable and disable by
default), and uncripple SQL.
