Slow dropping of partitions caused by full listing of storage descriptors (Sohan Jain via pauly) pauly : http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1188886 Files : * /hive/trunk/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java > Slow dropping of partitions caused by full listing of storage descriptors > ------------------------------------------------------------------------- > > Key: HIVE-2368 > URL: https://issues.apache.org/jira/browse/HIVE-2368 > Project: Hive > Issue Type: Bug > Components: Metastore > Reporter: Sohan Jain > Assignee: Sohan Jain > Fix For: 0.9.0 > > Attachments: HIVE-2368.1.patch > > > To determine if a column descriptor is unused, we call > listStorageDescriptorsWithCD(), which may return a big list of SDs. This can > severely slow down dropping partitions. > We can add a maximum number of SDs to return, and just ask for 1 SD, since we > are just doing an existential check. -- This message is automatically generated by JIRA.
