Subject [jira] Commented: (HIVE-918) Allow partition-wise file format
Date Tue, 10 Nov 2009 01:39:32 GMT

    [ https://issues.apache.org/jira/browse/HIVE-918?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12775238#action_12775238

He Yongqiang commented on HIVE-918:
-----------------------------------

bq. 1) Every partition has its own Storage Descriptor object which contains information about
file descriptors, serdes and other storage related information that a table can have. There
is no need to add more metadata to partition. 
Thanks! So we will not need to add new metadata into patition.
bq. 2) 
If we already filled all sd metadata of partitions. We will not need to add mnew, we can just
change the table's existing sd and use that for new partitions. I will check that.

Thanks for the information, Prasad!

> Right now all partitions in a hive table share the same file format. We should allow
partition wise file format.
