Vihang Karajgaonkar has uploaded a new patch set (#4). ( http://gerrit.cloudera.org:8080/16308 )
Change subject: IMPALA-4364: Query option to refresh updated partitions ...................................................................... IMPALA-4364: Query option to refresh updated partitions This patch introduces a new boolean query option REFRESH_UPDATED_HMS_PARTITIONS. When this query option is set the refresh table command reloads the partitions which have been modified in HMS in addition to adding [removing] the new [removed] partitions. In order to do this the refresh table command needs to fetch all the partitions instead of the just the partition names which can cause the performance of refresh table to degrade when the query option is set. However for certain use-cases currently there is no way to detect changed partitions using refresh table command. For instance, if certain partition locations have been changed, a refresh table will not update those partitions. Testing: 1. Added a new test which sets the query option and makes sure that the updated partitions from hive are reloaded after refresh table command. 2. Ran exhaustive tests with the patch.
