[jira] [Created] (HBASE-27988) NPE in AddPeerProcedure recovery

ruanhui created HBASE-27988:
-------------------------------

             Summary: NPE in AddPeerProcedure recovery
                 Key: HBASE-27988
                 URL: https://issues.apache.org/jira/browse/HBASE-27988
             Project: HBase
          Issue Type: Bug
          Components: Replication
    Affects Versions: 4.0.0-alpha-1
            Reporter: ruanhui
            Assignee: ruanhui
             Fix For: 3.0.0-alpha-4


AddPeerProcedure will restore syncReplicationPeerLock when replayed in master recovery, however the replicationPeerManager has not been initialized when replay procedure, which will cause a nullPointerException and master to abort.
{code:java}
@Override
protected void afterReplay(MasterProcedureEnv env) {
  // ......
  if (peerConfig.isSyncReplication()) {
    if (!env.getReplicationPeerManager().tryAcquireSyncReplicationPeerLock()) {
      throw new IllegalStateException(
        "Can not acquire sync replication peer lock for peer " + peerId);
    }
  }
}  {code}
