Subject [jira] [Commented] (HIVE-16671) LLAP IO: BufferUnderflowException may happen in very rare(?) cases due to ORC end-of-CB estimation
Date Tue, 16 May 2017 00:46:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16011558#comment-16011558

Sergey Shelukhin commented on HIVE-16671:
-----------------------------------------

The 3-byte check is related to the 3-byte CB header. I dbl checked, we hit BufferUnderflow
(no next byte) on the 3rd get.
I don't think it's related to the file header, that would have happened much earlier. I may
have more details tomorrow about the failure.
