[jira] [Created] (HBASE-21001) ReplicationObserver fails to load in
HBase 2.0.0
Wei-Chiu Chuang created HBASE-21001:
---------------------------------------
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 18:20:36,365 INFO org.apache.hadoop.hbase.regionserver.RegionServerCoprocessorHost: Table coprocessor loading is enabled
2018-08-02 18:20:36,365 ERROR org.apache.hadoop.hbase.regionserver.RegionServerCoprocessorHost: org.apache.hadoop.hbase.replication.regionserver.ReplicationObserver is not of type
RegionServerCoprocessor. Check the configuration of hbase.coprocessor.regionserver.classes
2018-08-02 18:20:36,366 ERROR org.apache.hadoop.hbase.coprocessor.CoprocessorHost: Cannot load coprocessor ReplicationObserver

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