DiskRangeList will not be 1 or 2 byte long right? If we can't read complete header in current DiskRangeList, worst case it will be in next contiguous DiskRangeList. Am I missing something here? Will be good to make it a separate method with tests (fake InStreams) if possible. > LLAP IO: BufferUnderflowException may happen in very rare(?) cases due to ORC end-of-CB estimation > -------------------------------------------------------------------------------------------------- > > Key: HIVE-16671 > URL: https://issues.apache.org/jira/browse/HIVE-16671 > Project: Hive > Issue Type: Bug > Reporter: Ravi Mutyala > Assignee: Sergey Shelukhin > Attachments: HIVE-16671.01.patch, HIVE-16671.patch > > -- This message was sent by Atlassian JIRA (v6.3.15#6346)
