HBase Cluster Setup

JDK version and hbase correspondence relationship

HBase Version	JDK 6	JDK 7	JDK 8
2	Not supported	Not supported	Yes
1.3	Not supported	Yes	Yes
1.2	Not supported	Yes	Yes
1.1	Not supported	Yes	Running with JDK 8 would work, but isn't well tested.
1	Not supported	Yes	Running with JDK 8 would work, but isn't well tested.
0.98	Yes	Yes	Running with JDK 8 works It is not a well tested. Building with JDK 8 would require removal of the deprecated remove () method of Thepoolmap class and is under consideration . See HBASE-7608 For more information on JDK 8 support.
0.94	Yes	Yes	N/A

Hadoop version Support matrix "S" = Supported "X" = Not supported "NT" = Not tested
The software versions we use here are as followsHadoop 2.7.1Hbase hbase-1.2.4jdk1.8.0_101
The first step, download the latest version from the Apache Foundation

HTTPS://mirrors.tuna.tsinghua.edu.cn/apache/hbase/1.2.4/hbase-1.2.4-bin.tar.gz

Step two , unzip to the server

TAR-ZXVF hbase-1.2. 4

The third step is to configure the HBase cluster to modify 3 files (first the ZK cluster is already installed) Note: Since HBase final data is stored in HDFs, Hadoop's hdfs-site.xml and core-site.xml need to be put into hbase/ Conf 1. Modify the hbase-env.sh on master

Export JAVA_HOME=/USR/JAVA/JDK1. 8. 0_101

Tells HBase to use the external ZK if using internal ZK, set to True (single-machine pseudo-distributed)

Export hbase_manages_zk=false

 is default . Export Hbase_heapsize=8g

2. Modify Hbase-site.xml

<configuration>    <property>            <name>hbase.rootdir</name>            <value>hdfs: // node1:9000/hbase</value>    </property>    <property>            <name>hbase.cluster.distributed</name>            <value >true</value>    </property>    <property>            <name> Hbase.zookeeper.quorum</name>            <value>node1:2181, Node2:2181, Node3:  2181</value>    </property></configuration>

3. Specify the machine as Regionserver and do not specify master separately. Where: on which machine to start, which is master, in the Regionservers file description to start the Hregionserver

Vim Regionserversnode1node2node3node4

Fourth step, copy the configured hbase files to the other nodes

Fifth Step:

1. Start the ZK for all hbase respectively./zkserver.sh start start the HDFs cluster start-dfs.sh start HBase and run on the master node: Star T-hbase.sh6. Accessing the hbase1.2.4 version management page through a browser node1:16010 (differs from version 0.98)7. To enable cluster reliability, start multiple hmaster (optional) hbase-daemon.sh start master
