[jira] [Commented] (HIVE-17698) FileSinkDesk.getMergeInputDirName() uses stmtId=0

    [ https://issues.apache.org/jira/browse/HIVE-17698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16192069#comment-16192069 ] 

Eugene Koifman commented on HIVE-17698:
---------------------------------------

In fact,
FileSinkOperator.initializeBucketPaths(int filesIdx, String taskId, boolean isNativeTable,
        boolean isSkewedStoredAsSubDirectories)
calls           
String subdirPath = AcidUtils.deltaSubdir(txnId, txnId, stmtId);
which means it should already generate a different delta/ (by suffix) for each FileSinkOperator

> this is certainly wrong for multi statement txn but may also affect writes from Union All queries if these are made to follow full Acid convention
> _return new Path(root, AcidUtils.deltaSubdir(txnId, txnId, 0));_
