> Key: HBASE-21001
> URL: https://issues.apache.org/jira/browse/HBASE-21001

> 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:
> {quote}
> 2018-08-02 18:20:36,365 INFO
> org.apache.hadoop.hbase.regionserver.RegionServerCoprocessorHost: System
> coprocessor loading is enabled
> 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

> 2018-08-02 18:20:36,366 ERROR
> org.apache.hadoop.hbase.coprocessor.CoprocessorHost: Cannot load coprocessor
> ReplicationObserver
> {quote}
> It looks like this was broken by HBASE-17732 to me, but I could be wrong.
