Review request for hive, Mohit Sabharwal and Naveen Gangam.
Changes
-------
Addressed feedback changes from Kapil and Reuben.
Bugs: HIVE-13884
https://issues.apache.org/jira/browse/HIVE-13884
Repository: hive-git
Description
-------
The patch verifies the # of partitions a table has before fetching any from the
metastore. I
t checks that limit from 'hive.limit.query.max.table.partition'.
A limitation added here is that the variable must be on hive-site.xml in order
to work, and it does not accept to set this through beeline because
HiveMetaStore.java does not read the variables set through beeline. I think it
is better to keep it this way to avoid users changing the value on fly, and
crashing the metastore.
Another change is that EXPLAIN commands won't be executed either. EXPLAIN
commands need to fetch partitions in order to create the operator tree. If we
allow EXPLAIN to do that, then we may have the same OOM situations for large
partitions.
