错误：org.apache.hadoop.hbase.MasterNotRunningException：null + hbase + hadoop [英] ERROR: org.apache.hadoop.hbase.MasterNotRunningException: null+hbase+hadoop

问题描述

我最近配置了两台机器的hadoop集群（在ubuntu上）。到目前为止它工作正常。但是当我尝试在上面的hadoop集群上配置hbase时，它显示错误。
这是我做的，

我有两台机器。
192.168.1.110 Hadoop master
192.168.1.111 Hadoop从站

conf / hbase-env.sh

export JAVA_HOME = / usr / lib / jvm / java-6-sun-1.6.0.22
export HBASE_CLASSPATH = / home / hadoop / hadoop-0.20.2 / conf
export HBASE_MANAGES_ZK = true

hbase-site.xml

hbase.master-> 192.168.1.110:54310（与hadoop相同master：port）
hbase.rootdir-> hdfs：//192.168.1.110：54310 / hbase
hbase.cluster.distributed-> true
hbase.zookeeper.quorum-> 192.168.1.110 ，192.168.1.111

和区域srevers，

192.168.1.111

hbase，我试图从hbase shell运行命令

hbase（main）：001：0> list
TABLE

它显示

错误：org.apache.hadoop.hbase.MasterNotRunningException：null

请帮我解决问题
在此先感谢

解决方案

错误是自我xplaining。如果您在主机（192.168.1.110）计算机上使用hadoop用户执行 jps ，您将看到HMaster未运行。请检查HMaster日志，看看它为什么失败。

I have recently configured hadoop cluster with two machines(on ubuntu). It works fine so far. But when i try to configure hbase on the above hadoop cluster, it shows error. Here is what i did,

i have two machines. 192.168.1.110 Hadoop master 192.168.1.111 Hadoop slave

conf/hbase-env.sh

export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.22 export HBASE_CLASSPATH=/home/hadoop/hadoop-0.20.2/conf export HBASE_MANAGES_ZK=true

hbase-site.xml

hbase.master->192.168.1.110:54310(Same as hadoop master:port) hbase.rootdir->hdfs://192.168.1.110:54310/hbase hbase.cluster.distributed->true hbase.zookeeper.quorum->192.168.1.110,192.168.1.111

And region srevers,
192.168.1.111

After starting hbase, i tried to run the command from hbase shell

hbase(main):001:0> list TABLE
It shows

ERROR: org.apache.hadoop.hbase.MasterNotRunningException: null

Please help me up solving the issue Thanks in advance

解决方案

The error is self explaining. if you do jps with the hadoop user on your master(192.168.1.110) machine you would see that HMaster is not running. Please check the HMaster logs to see why it failed.
