Question

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。我让主人没有运行错误，但Jsp清楚地表明它正在运行。启动Hadoop和Hbase之后。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，我收到以下错误。

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

<configuration>
    <property>

        <value>/Users/yeshwanthvenkatesh/Documents/Hadoop/Daemons/zookeeper</value>
    </property>
</configuration>

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

我不管理Zookeeper实例，所以我在hbase-env.sh中将其设置为true。我做错了什么？日志也没有多大帮助。

Answer 1

从您的日志和主机文件中，我发现您的配置没有任何问题。因此版本不兼容可能存在问题。我也面临同样的问题所以我改变了我的hbase版本下载hbase-0.94.11以及zookeeper-3.4.3，hadoop 1.0.1并且工作正常。虽然我没有找到任何具体原因来解决这个问题，但它运作良好。

Answer 2

如果您使用hbase 0.94，则存在错误。您需要在roodir

中使用rootdir代替hbase-site.xml

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

Answer 3

最好使用HBx的最新稳定版本1.2倍。 1.1x也在流行使用。如果您尝试在本地计算机上运行，则不需要单独启动hadoop和Hbase。

从https://hbase.apache.org/

下载最新版本

Answer 4

您的名称节点或数据节点似乎处于安全模式。因此，我们需要离开安全模式，以便将数据插入hdfs或hdfs中的hbase表。我们可以使用以下命令退出namenode或datanode的安全模式：

hdfs dfsadmin -safemode leave

成功执行后，将显示以下消息：

安全模式为关闭

在发生上述错误之后，hbase shell正常运行。

Answer 5

HBase主节点未启动。一切似乎都已正确配置，因此您需要执行：

$ ./bin/start-hbase.sh

让Master没有运行异常
