---------------------------------------
Summary: ReplicationObserver fails to load in HBase 2.0.0
Key: HBASE-21001
URL: https://issues.apache.org/jira/browse/HBASE-21001
Project: HBase
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Wei-Chiu Chuang
ReplicationObserver was added in HBASE-17290 to prevent "Potential loss of data
for replication of bulk loaded hfiles".
I tried to enable bulk loading replication feature
(hbase.replication.bulkload.enabled=true and configure
hbase.replication.cluster.id) on a HBase 2.0.0 cluster, but the RegionServer
started with the following error:

2018-08-02 18:20:36,366 ERROR

It looks like this was broken by HBASE-17732 to me, but I could be wrong.
