环境:Ubuntu 14.04,hadoop-2.2.0,hbase-0.98.7
当我启动hadoop和hbase(单节点模式)时,两者都成功(我也检查网站8088为hadoop,60010为hbase)
jps
4507 SecondaryNameNode
5350 HRegionServer
4197 NameNode
4795 NodeManager
3948 QuorumPeerMain
5209 HMaster
4678 ResourceManager
5831 Jps
4310 DataNode
但是当我检查hbase-hadoop-master-localhost.log时,我发现了以下信息
2014-10-23 14:16:11,392 INFO [main-SendThread(localhost:2181)] zookeeper.ClientCnxn: Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)
2014-10-23 14:16:11,426 INFO [main-SendThread(localhost:2181)] zookeeper.ClientCnxn: Socket connection established to localhost/127.0.0.1:2181, initiating session
我有谷歌很多网站的未知错误问题,但我无法解决这个问题…
以下是我的hadoop和hbase配置
Hadoop:

regionserver内容:localhost
我的/ etc / hosts内容:
127.0.0.1 localhost
#127.0.1.1 localhost
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
我尝试了很多方法来解决它,但都失败了,请帮我解决,我真的需要知道如何解决.
最初,我运行mapreuce程序,当地图67%减少0%时,它打印出一些INFO,一些INFO如下:
14/10/23 15:50:41 INFO zookeeper.ZooKeeper: Initiating client connection, connectString=localhost:2181 sessionTimeout=60000 watcher=org.apache.hadoop.hbase.client.HConnectionManager$ClientZKWatcher@ce1472
14/10/23 15:50:41 INFO zookeeper.ClientCnxn: Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)
14/10/23 15:50:41 INFO zookeeper.ClientCnxn: Socket connection established to localhost/127.0.0.1:2181, initiating session
14/10/23 15:50:41 INFO zookeeper.ClientCnxn: Session establishment complete on server localhost/127.0.0.1:2181, sessionid = 0x1493be510380007, negotiated timeout = 40000
14/10/23 15:50:43 INFO mapred.LocalJobRunner: map > sort
14/10/23 15:50:46 INFO mapred.LocalJobRunner: map > sort
然后它崩溃..我认为程序可能在死锁,这就是我想解决上面的zookeeper问题.
如果想要我在hadoop或hbase或其他设置的其他配置文件,请告诉我,我会发布.
谢谢!
最佳答案 我不认为zookeeper是你的问题.您应该查看其他日志以获取有关地图/减少作业状态的更多信息.通过纱线作业跟踪器ui检查datanode和namenode日志中的错误以及纱线日志消息.
ZooKeeper消息
这些消息来自zookeeper尝试连接Zookeeper sasl客户端.如果未配置sasl,则客户端仍可以连接,但不会对连接进行身份验证.
错误消息来自此文件
ZooKeeperSaslClient.java
150 // The user did not override the default context. It might be that they just don't intend to use SASL,
151 // so log at INFO, not WARN, since they don't expect any SASL-related information.
152 String msg = "Will not attempt to authenticate using SASL ";
153 if (runtimeException != null) {
154 msg += "(" + runtimeException + ")";
155 } else {
156 msg += "(unknown error)";
157 }
158 this.configStatus = msg;
159 this.isSASLConfigured = false;
160 }
如果你想摆脱错误,你必须配置zookeeper使用sasl.抱歉,对于zookeeper的配置sasl没有任何经验.
