Example 6 with SyncReplicationState

use of org.apache.hadoop.hbase.replication.SyncReplicationState in project hbase by apache.

the class ReplicationPeerManager method addPeer.

public void addPeer(String peerId, ReplicationPeerConfig peerConfig, boolean enabled) throws ReplicationException {
    if (peers.containsKey(peerId)) {
        // this should be a retry, just return
        return;

    peerConfig = ReplicationPeerConfigUtil.updateReplicationBasePeerConfigs(conf, peerConfig);
    ReplicationPeerConfig copiedPeerConfig = ReplicationPeerConfig.newBuilder(peerConfig).build();
    SyncReplicationState syncReplicationState = copiedPeerConfig.isSyncReplication() ? SyncReplicationState.DOWNGRADE_ACTIVE : SyncReplicationState.NONE;
    peerStorage.addPeer(peerId, copiedPeerConfig, enabled, syncReplicationState);
    peers.put(peerId, new ReplicationPeerDescription(peerId, enabled, copiedPeerConfig, syncReplicationState));
