无法在单个节点上以伪分布式模式启动Hbase主服务器

标签: hadoop hbase cloudera

我刚开始学习Hadoop。

我在CentOS上使用 Hbase 0.94.12 在Cloudera CDH4上运行 Hadoop 2.0.0

我运行命令服务hbase-master start,它只启动服务器几秒钟。

jps显示此结果:

29300 SecondaryNameNode
3354 NodeManager
3032 RunJar
2957 RunJar
2552 HRegionServer
4016 Jps
3432 ResourceManager
2312 HQuorumPeer
30345 QuorumPeerMain
29228 NameNode
2671 JobHistoryServer
29157 DataNode

此外,这是确切的错误日志

我的hbase-site.xml配置如下:

这是我的hbase-env.sh文件:
