[jira] [Comment Edited] (HIVE-18817) ArrayIndexOutOfBounds
exception during read of ACID table.
[ https://issues.apache.org/jira/browse/HIVE-18817?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16379801#comment-16379801 ]

----------------------------------------------------------------
patch1 fixes the issue
The test case generates a file with 2 stripes. w/o the fix to OrcRecorUpdater.KeyIndexBuilder, the hive.acid.key.index in the file has 1 entry - with the fix it has 2 and no AIOOBException happens.
todo: file an ORC ticket to fix this in ORC.

> Have a JUnit test that appears to produce a similar stack trace - looks like this occurs if there is an OrcSplit of an ACID table where the split offset is beyond the starting offset of the last stripe in the ORC file.
