--------------------------------
Summary: when execute shell cmd "disable_peer peerId"，the master
web UI show a wrong number of SizeOfLogQueue
Key: HBASE-24781
URL: https://issues.apache.org/jira/browse/HBASE-24781
Project: HBase
Issue Type: Bug
Components: Replication
Affects Versions: 2.2.5
Reporter: leizhang
Supposed that we have an source peer with id 1, when execute shell cmd
disable_peer '1' , then i can see the SizeOfLogQueue metric of all
regionservers +1 , after 10 times disable_peer ops , it will increase to
11, and it will never decrease to 1 in fulture .
I can see the function ReplicationSourceManager.refreshSources(peerId) called
, it will enqueue the current wals to the source , maybe when the current wal
is already in the replication queue , we try to and a duplicated wal to the
source ,and cause the same wal increase the SizeOfLogQueue twice ? thx
