Subject [jira] [Updated] (HBASE-14777) Replication fails with IndexOutOfBoundsException
Date Wed, 18 Nov 2015 01:01:13 GMT

     [ https://issues.apache.org/jira/browse/HBASE-14777?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ashu Pachauri updated HBASE-14777:
    Attachment: HBASE-14777-1.patch

I am not sure how [~Bhupendra] actually encountered the issue, because there is another bug
that actually masks the issue mentioned here.

Doing Future<Integer>#get() returns an Integer object and using this Integer object
in ArrayList#remove calls the overloaded ArrayList#remove(Object) method (no auto-unboxing
will happen since this method exists), which basically means that it does not remove anything.

However, if you replace Integer with an int , you will encounter the ArrayIndexOutofBoundsException.

Anyways, I fixed both the issues and added a simple unit test to test inter cluster replication
on mini clusters.
