Review request for hive and Ashutosh Chauhan. Bugs: HIVE-14462 https://issues.apache.org/jira/browse/HIVE-14462 Repository: hive-git Description ------- Metastore already does all the validations. Lots of MS calls are made just before add_partitions to double check if the partitions exists. This impacts perf when large number of partitions are present. Diffs ----- metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java 38c0eed Diff: https://reviews.apache.org/r/50888/diff/ Testing ------- Thanks, Rajesh Balamohan
