Ning Zhang updated HIVE-1394: ----------------------------- Attachment: HIVE-1394.2.patch Added a check in SemanticAnalyzer to throw an exception when HOLD_DDLTIME is specified in dynamic partition insert or non-existence static partitions. A negative test case is also added. > do not update transient_lastDdlTime if the partition is modified by a > housekeeping operation > -------------------------------------------------------------------------------------------- > > Key: HIVE-1394 > URL: https://issues.apache.org/jira/browse/HIVE-1394 > Project: Hadoop Hive > Issue Type: Improvement > Components: Query Processor > Reporter: Namit Jain > Assignee: Ning Zhang > Attachments: HIVE-1394.2.patch, HIVE-1394.patch > > > Currently. purging looks at the hdfs time to see the last time the files got > modified. > It should look at the metastore property instead - these are facebook > specific utilities, which do not require any changes to hive. > However, in some cases, the operation might be performed by some housekeeping > job, which should not modify the timestamp. > Since, hive has no way of knowing the origin of the query, it might be a good > idea to add a new hint which specifies that the > operation is a cleanup operation, and the timestamp in the metastore need not > be touched for that scenario. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
