Dip Kharod updated PIG-3883:
----------------------------
Description:
I'm using HCatStorer to write to external Hive table with partition from Pig
and have the following different use cases:
1) Need to overwrite (aka, refresh) data into table: Currently I end up doing
this outside (drop partition and delete HDFS folder) of Pig which is very
painful and error-prone
2) Need to append (aka, add new file) data to the Hive external
table/partition: Again, I end up doing this outside of Pig by copying file in
appropriate folder
It would be very productive for the developers to have both options in
HCatStorer.
