本地文件系统上的独立 HBase 出现 zookeeper 错误? [英] Stand alone HBase on local file system getting zookeeper error?
问题描述
大家好，我正在尝试按照 快速启动 HBase 并启动 HBase在本地文件系统上(不使用 HDFS)但是，当我使用 ./hbase shell 启动 shell 并键入status"时，出现 zookeeper 错误?！
hbase(main):001:0>地位14/01/07 12:44:48 错误 zookeeper.RecoverableZooKeeper:3 次重试后，ZooKeeper 存在失败14/01/07 12:44:48 WARN zookeeper.ZKUtil: hconnection 无法在 znode (/hbase/hbaseid) 上设置观察者org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for/hbase/hbaseid//…………等等……这是我的配置文件(hbase-site.xml)

问题出在这里(在你的 conf - conf/hbase-site.xml):
hbase.zookeeper.quorum <value>本地主机</value>由于错误ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries"表明您的 zookeeper.quorum 指令存在问题.或者在启动 HBase shell 之前，您可以使用以下命令验证 ZKQuorum 是否已启动:
$ jps该命令将列出机器上的所有 java 进程，即可能的输出必须是:
62019 日元61098 HMaster61233 HRegionServer61003 HQuorumPeer<小时>
解决方案:
在你的 HBase 目录中，首先停止 HBase:
$ ./bin/stop-hbase.sh如果您正在尝试制定独立 HBase"示例 - 坚持示例中提供的最低配置:
<预><代码><配置><财产><name>hbase.rootdir</name><value>file:///home/adio/workspace/hadoop/hbase/directories/hbase</value></属性><财产><name>hbase.zookeeper.property.dataDir</name><value>/home/adio/workspace/hadoop/hbase/directories/zookeeper</value></属性></配置>即你的 conf/hbase-site.xml 应该有以上内容.
一旦设置，现在再次启动 HBase:
$ ./bin/start-hbase.shHi guys I am trying to follow the quick start of HBase and start an HBase on the local file system( without using HDFS ) However when I start the shell using ./hbase shell and type "status" I get zookeeper error ?!
hbase(main):001:0> status
14/01/07 12:44:48 ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries
14/01/07 12:44:48 WARN zookeeper.ZKUtil: hconnection Unable to set watcher on znode (/hbase/hbaseid)
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid
//......... ect .....
Here is my config file ( hbase-site.xml )

<description>Comma separated list of servers in the ZooKeeper Quorum.
For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
By default this is set to localhost for local and pseudo-distributed modes
of operation. For a fully-distributed setup, this should be set to a full
list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in hbase-env.sh
this is the list of servers which we will start/stop ZooKeeper on.

Any suggestions ?
The problem is here (in your conf - conf/hbase-site.xml):
<name>hbase.zookeeper.quorum</name>
<value>localhost</value>
As the error "ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries" indicates there is some problem with your zookeeper.quorum directive. Or Before staring the HBase shell you can verify if the ZKQuorum is up, using:
$ jps
the command will list all the java processes on the machine i.e. the probable output has to be:
62019 Jps
61098 HMaster
61233 HRegionServer
61003 HQuorumPeer
Solution:
In your HBase directory, first stop the HBase:
$ ./bin/stop-hbase.sh
If you're trying to work out the 'standalone HBase' example - stick to the minimum conf provided in the example:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///home/adio/workspace/hadoop/hbase/directories/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/adio/workspace/hadoop/hbase/directories/zookeeper</value>
</property>
</configuration>
i.e. your conf/hbase-site.xml should have the above content.
Once set, now start the HBase again:
$ ./bin/start-hbase.sh
