[jira] [Commented] (HIVE-10567) partial scan for rcfile table
doesn't work for dynamic partition
[ https://issues.apache.org/jira/browse/HIVE-10567?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16076672#comment-16076672 ]
Ashutosh Chauhan commented on HIVE-10567:
-----------------------------------------
[~prasanth_j] Unfortunately partial partition spec partition(ds,hr) still needs to be specified if stats collection on all partitions is desired. We shall improve that syntax in a followup jira.
In the meanwhile the bug specified here for partialscan is relevant and need to be fixed.

> HIVE-3958 added support for partial scan for RCFile. This works fine for static partitions (for example: analyze table analyze_srcpart_partial_scan PARTITION(ds='2008-04-08',hr=11) compute statistics partialscan).
> For dynamic partition, the analyze files with an IOException "java.io.IOException: No input paths specified in job":
> hive> ANALYZE TABLE testtable PARTITION(col_varchar) COMPUTE STATISTICS PARTIALSCAN;
