独立HBase本地文件系统获取zookeeper错误？ [英] Stand alone HBase on local file system getting zookeeper error?
问题描述
我正在尝试遵循 HBase快速入门并启动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，我得到zookeeper错误？！
hbase（main）：001：0>状态
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无法设置观察者在znode（/ hbase / hbaseid）
org.apache.zookeeper.KeeperException $ ConnectionLossException：KeeperErrorCode = ConnectionLoss for / hbase / hbaseid
// ......... ect .....
这是我的配置文件（hbase-site.xml）
<？xml version =1.0？>
<？xml-stylesheet type =text / xslhref =configuration.xsl？>

有何建议？
问题在这里（在你的conf中 -
conf / hbase-site.xml ）： <名称>&hbase.zookeeper.quorum LT; /名称>
<值>本地主机< /值>
由于错误错误zookeeper.RecoverableZooKeeper：ZooKeeper在3次重试后失败表示您的 zookeeper.quorum 指令有问题。或者在观看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，即可能的输出必须为：
62019 Jps
61098 HMaster
61233 HRegionServer
61003 HQuorumPeer
解决方案：
你的HBase目录，首先停止HBase：
$ ./bin/stop-hbase.sh
如果您正在尝试制定'独立HBase'示例 - 请坚持示例中提供的最小配置：
< configuration>
<属性>
<名称> hbase.rootdir< /名称>
< value> file：/// home / adio / workspace / hadoop / hbase / directories / hbase< / value>
< / property>
<属性>
<名称> hbase.zookeeper.property.dataDir< / name>
<值> / home / adio / workspace / hadoop / hbase / directories / zookeeper< /值>
< / property>
< / configuration>
即你的 conf / hbase-site.xml 应该有上述内容。
设置完毕后，再次启动HBase ：
$ ./bin/start-hbase.sh
Hi 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 )
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<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
