[jira] [Commented] (FLINK-18659) FileNotFoundException when writing
Hive orc tables
[ https://issues.apache.org/jira/browse/FLINK-18659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17162044#comment-17162044 ]
Rui Li commented on FLINK-18659:
--------------------------------
I managed to reproduce the issue and did some debugging. In Hive 2.3.4, the in-progress file is created when Hive creates the Orc writer. In Hive 1.1.0, it seems the file is not created even after the first record is written. When a {{Bucket}} receives the first record, it creates the writer and writes this record with the writer. And on the 2nd record, the {{Bucket}} checks the underlying file size to see if rolling is needed and this is when we hit the exception because the file is not yet created.

> This maybe due to lazy init in Orc writer. Until first record comes, orc writer not create this file.
