Jay Zhuang commented on CASSANDRA-14066:
----------------------------------------
It's a real issue with [{{CommitLogReplayer.replayFiles()}}|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/commitlog/CommitLogReplayer.java#L145]. When for CDC data, it's handling the wrong file (the right one + 1, and in the wrong list: [{{CommitLogReplayer.java:151}}|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/commitlog/CommitLogReplayer.java#L151]).
Sometimes, it's causing the following exception:
{noformat}
java.lang.ArrayIndexOutOfBoundsException: 4

{noformat}
Here is the fix, please review:
