【hbase】hbase-2.2.1配置独立的zookeeper的安装与测试
下载hbase-2.2.1-bin.tar.gz并执行安装命令：html
[hadoop@hadoop01 ~]$ tar -zxvf hbase-2.2.1-bin.tar.gz
查看安装目录：java
[hadoop@hadoop01 ~]$ cd hbase-2.2.1
[hadoop@hadoop01 hbase-2.2.1]$ ls -l

进入安装目录下conf，编辑hbase-env.sh、hbase-site、regionservers文件：node
[hadoop@hadoop01 hbase-2.2.1]$ cd conf
[hadoop@hadoop01 conf]$ ls
hadoop-metrics2-hbase.properties hbase-site.xml
hbase-env.cmd log4j.properties
hbase-env.sh regionservers
hbase-policy.xml
hbase-env.sh文件linux
[hadoop@hadoop01 conf]$ gedit hbase-env.sh
修改的内容：
export JAVA_HOME=/usr/java/jdk1.8.0_11/
export HBASE_MANAGES_ZK=false #flase表示使用独立的zookeeper
hbase-site文件：web
[hadoop@hadoop01 conf]$ gedit hbase-site.xml 编辑内容： <configuration> <property> <name>hbase.master</name>#hbasemaster的主机和端口 <value>hadoop01:16010</value> </property> <property> <name>hbase.rootdir</name> <value>hdfs://hadoop01:9000/hbase</value> </property> <property> <name>hbase.cluster.distributed</name>#是否分布式运行，false即为单机 <value>true</value> </property> <property> <name>hbase.zookeeper.quorum</name> <value>hadoop01,hadoop02,hadoop03</value> </property> <property> <name>hbase.master.maxclockskew</name> <value>180000</value> </property>
<!--hbase.unsafe.stream.capability.enforce：使用本地文件系统设置为false，使用hdfs设置为true。
但根据HBase 官方手册的说明：HBase 从2.0.0 开始默认使用的是asyncfs。--> <property> <name>hbase.unsafe.stream.capability.enforce</name> <value>false</value>
</property>
</configuration>#共享目录，持久化hbase数据#zookeeper地址#时间同步容许的时间差<description> Controls whether HBase will check for stream capabilities (hflush/hsync). Disable this if you intend to run on LocalFileSystem, denoted by a rootdir with the 'file://' scheme, but be mindful of the NOTE below. WARNING: Setting this to false blinds you to potential data loss and inconsistent system state in the event of process and/or node failures. If HBase is complaining of an inability to use hsync or hflush it's most likely not a false positive. </description>
注：咱们测试环境里用的是HBase 2.2.1, 因此这里虽然是集群环境，也直接将该参数设置false，而后重启Hbase Master，恢复正常。 或者使用版本小于2.0.0的HBase，也能够避免出现这种错误shell
regionservers文件：apache
[root@hadoop01 conf]# gedit regionservers
编辑内容为：
hadoop02
hadoop03
配置环境变量：bash
[hadoop@hadoop01 ~]$ gedit ~/.bash_profile
文本须要添加的内容：
#hbase
export HBASE_HOME=/home/hadoop/hbase-2.2.1
export PATH=$HBASE_HOME/bin:$PATH
export HADOOP_CLASSPATH=$HBASE_HOME/lib/*
[hadoop@hadoop01 ~]$ source ~/.bash_profile
拷贝到其余节点上：
[hadoop@hadoop01 ~]$ scp -r hbase-2.2.1 hadoop02:~/
[hadoop@hadoop01 ~]$ scp -r hbase-2.2.1 hadoop03:~/
启动中止hbase命令：app
[hadoop@hadoop01 ~]$ cd ~/hbase-2.2.1
[hadoop@hadoop01 hbase-2.2.1]$ bin/start-hbase.sh --启动hbase
[hadoop@hadoop01 hbase-2.2.1]$ jps --显示进程
16720 ResourceManager
16866 NodeManager
19427 QuorumPeerMain --zookeeper进程
22387 Jps
16455 SecondaryNameNode
16075 NameNode
22062 HMaster --hbase进程
[hadoop@hadoop01 hbase-2.2.1]$ bin/stop-hbase.sh
注：启动报以下异常webapp
java.lang.IllegalStateException: The procedure WAL relies on the ability to hsync for proper operation during component failures, but the underlying filesystem does not support doing so. Please check the config value of 'hbase.procedure.store.wal.use.hsync' to set the desired level of robustness and ensure the config value of 'hbase.wal.dir' points to a FileSystem mount that can provide it.
hbase-site.xml增长配置
<property>
<name>hbase.unsafe.stream.capability.enforce</name>
<value>false</value>
</property>
hbase网页版网：http://192.168.1.100:16010/master-status
注：HBASE1.0以后的版本web端访问的接口变动为16010，192.168.1.100为个人linux端口地址
启动并测试hbase：
[hadoop@hadoop01 hbase-2.2.1]$ jps --查看进程HMaster是否启动
11264 HMaster
11573 Jps
8566 DataNode
8426 NameNode
9642 QuorumPeerMain
8795 SecondaryNameNode
9053 ResourceManager
9197 NodeManager
[hadoop@hadoop01 hbase-2.2.1]$ hbase shell --进入shell模式
