Hi, I am using hbase-0.98.15-hadoop2 and hbase-indexer from lily ( http://ngdata.github.io/hbase-indexer/).
I am seeing below error when I add my indexer: 2015-10-22 14:08:27,468 INFO [regionserver60020-EventThread] replication.ReplicationTrackerZKImpl: /hbase/replication/peers znode expired, triggering peerListChanged event 2015-10-22 14:08:27,473 ERROR [regionserver60020-EventThread] regionserver.ReplicationSourceManager: Error while adding a new peer org.apache.hadoop.hbase.replication.ReplicationException: Error adding peer with id=Indexer_newtest2 at org.apache.hadoop.hbase.replication.ReplicationPeersZKImpl.createAndAddPeer(ReplicationPeersZKImpl.java:386) at org.apache.hadoop.hbase.replication.ReplicationPeersZKImpl.peerAdded(ReplicationPeersZKImpl.java:358) at org.apache.hadoop.hbase.replication.regionserver.ReplicationSourceManager.peerListChanged(ReplicationSourceManager.java:514) at org.apache.hadoop.hbase.replication.ReplicationTrackerZKImpl$PeersWatcher.nodeChildrenChanged(ReplicationTrackerZKImpl.java:189) at org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher.process(ZooKeeperWatcher.java:468) at org.apache.zookeeper.ClientCnxn$EventThread.processEvent(ClientCnxn.java:522) at org.apache.zookeeper.ClientCnxn$EventThread.run(ClientCnxn.java:498) Caused by: org.apache.hadoop.hbase.replication.ReplicationException: Error starting the peer state tracker for peerId=Indexer_newtest2 at org.apache.hadoop.hbase.replication.ReplicationPeersZKImpl.createPeer(ReplicationPeersZKImpl.java:454) at org.apache.hadoop.hbase.replication.ReplicationPeersZKImpl.createAndAddPeer(ReplicationPeersZKImpl.java:384) ... 6 more Caused by: org.apache.zookeeper.KeeperException$DataInconsistencyException: KeeperErrorCode = DataInconsistency at org.apache.hadoop.hbase.zookeeper.ZKUtil.convert(ZKUtil.java:2063) at org.apache.hadoop.hbase.replication.ReplicationPeerZKImpl.startStateTracker(ReplicationPeerZKImpl.java:85) at org.apache.hadoop.hbase.replication.ReplicationPeersZKImpl.createPeer(ReplicationPeersZKImpl.java:452) ... 7 more Caused by: org.apache.hadoop.hbase.exceptions.DeserializationException: Missing pb magic PBUF prefix at org.apache.hadoop.hbase.protobuf.ProtobufUtil.expectPBMagicPrefix(ProtobufUtil.java:270) at org.apache.hadoop.hbase.replication.ReplicationPeerZKImpl.parseStateFrom(ReplicationPeerZKImpl.java:243) at org.apache.hadoop.hbase.replication.ReplicationPeerZKImpl.isStateEnabled(ReplicationPeerZKImpl.java:232) at org.apache.hadoop.hbase.replication.ReplicationPeerZKImpl.readPeerStateZnode(ReplicationPeerZKImpl.java:90) at org.apache.hadoop.hbase.replication.ReplicationPeerZKImpl.startStateTracker(ReplicationPeerZKImpl.java:83) ... 8 more My Hbase-site.xml: <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <!-- /** * Copyright 2010 The Apache Software Foundation * * Licensed to the Apache Software Foundation (ASF) under one * or more contributor license agreements.
