[jira] [Commented] (HIVE-14114) Ensure RecordWriter in streaming API is using the same UserGroupInformation as StreamingConnection

["Eugene Koifman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-14114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15364965#comment-15364965 ] 

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.

> currently both DelimitedInputWriter and StrictJsonWriter perform some Metastore access operations but without using UGI created by the caller for Metastore operations made by matching StreamingConnection & TransactionBatch
