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 02:34:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16011656#comment-16011656
] 

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

[~prasanth_j] btw, the first patch fixed the original issue. For that case, the new patch
would behave like the original. The corner case to the corner case, where 3 bytes of length
are present over multiple buffers, is handled in 02 patch. Unfortunately we don't have repro
for that and it might be impossible (perhaps if length falls on ZCR boundary with ZCR enabled?)
