Ashu Pachauri updated HBASE-14777:
----------------------------------
Attachment: HBASE-14777-1.patch
V1:
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.
