Eugene Koifman commented on HIVE-14114:
---------------------------------------
The patch modifies the API such that Writer c'tor takes StreamingConnection as
a parameter and it will use the UGI (if any) from the connection to perform
metastore operations. This way everything is consistent in that all
operations/objects use the same UserGroupInformation which was supplied by
API's caller.
> Ensure RecordWriter in streaming API is using the same UserGroupInformation
> as StreamingConnection
