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!
