我一直在努力让 Hbase 在我的机器上工作。我相信我的设置有问题，我无法修复它。我得到 master not running 错误，但 Jsp 清楚地显示它正在运行。启动 Hadoop 和 Hbase 后。我做了JPS

yeshwanthvenkatesh@mymachineip /usr/local/Cellar/hbase/0.94.4/bin (master)$ jps
1609 Main
715 DataNode
985 TaskTracker
614 NameNode
886 JobTracker
1463 HRegionServer
1263 HQuorumPeer
814 SecondaryNameNode
1695
1349 HMaster
1842 Jps

当我尝试在 Hbase shell 中调用命令时，出现以下错误。

hbase(main):001:0> list
TABLE
2013-04-25 16:20:28.933 java[1609:1703] Unable to load realm info from SCDynamicStore

ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:

  hbase> list
  hbase> list 'abc.*'

hbase(main):002:0> scan 'ResultStore'
ROW                                                  COLUMN+CELL
13/04/25 16:26:13 INFO ipc.HBaseRPC: Problem connecting to server: mymachineip/129.10.3.181:60020

这是我的 site.xml

这是我的 etc/hosts 文件

127.0.0.1       localhost
129.10.3.181  mymachineip
255.255.255.255 broadcasthost
# For Hadoop
# 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

我没有管理 Zookeeper 实例，所以我在我的 hbase-env.sh 中将其设置为 true。我做错了什么？日志也没有太大帮助。

从您的日志和主机文件中，我看不出您的配置有任何问题。所以可能是版本不兼容的问题。我也遇到了同样的问题，所以我更改了我的 hbase 版本，下载了 hbase-0.94.11 以及 zookeeper-3.4.3、hadoop 1.0.1 并且工作正常。虽然我没有找到问题的任何具体原因，但它工作正常。

HBase Master 节点未启动。一切似乎都已正确配置，因此您需要执行：

$ ./bin/start-hbase.sh

看来您的名称节点或数据节点处于安全模式。所以我们需要离开安全模式在hdfs中插入数据或者在hdfs中插入hbase表。我们可以使用以下命令离开namenode或datanode的安全模式：

hdfs dfsadmin -safemode leave

成功执行后，将显示此消息：

安全模式已关闭

并且在没有发生上述错误并且 hbase shell 正常运行之后。

如果您正在使用hbase 0.94，则存在错误。您需要使用roodir而不是rootdirinhbase-site.xml

<property>
    <name>hbase.roodir</name>
    <value>hdfs://localhost:9000/hbase</value>
</property>

最好使用 HBase 的最新稳定版本，即 1.2x。1.1x 也很流行。如果您尝试在本地计算机上运行 hadoop 和 Hbase，则无需单独启动它。

从https://hbase.apache.org/下载最新版本
