Checking hdfs:///tmp/jdere/testdir/bucket_00002 - acid key index is invalid
Checking hdfs:///tmp/jdere/testdir/bucket_00003 - acid key index is invalid
$ bin/hive --service fixacidkeyindex --recover /tmp/jdere/testdir
Recovering hdfs:///tmp/jdere/testdir/bucket_00000
Fixed acid key index for hdfs:///tmp/jdere/testdir/bucket_00000

> While HIVE-18817 will create new ORC Acid files from hitting the ArrayIndexOutOfBounds issue, existing files created before HIVE-18817 will still cause this issue. If there are delta directories then one way to generate new files is to perform a major compaction. But this does not work if there are no delta directories for the table/partition.
> Add a tool to fix the Acid ORC files directly in the case that a compaction cannot be performed.
