HBase (Distributed database) installation configuration for Hadoop series

 <configuration>      <property>           <name>hbase.rootdir</name>r           <value>hdfs://hdfs-master:9000/hbase</value>          //must be consistent with your Hadoop hostname and port number; HBase This item does not recognize the machine IP and can only be used with machine hostname     </ property>      <property>           <name>hbase.cluster.distributed</name>           <value>true</value>      </property>       <property>          < name>hbase.zookeeper.quorum</name>          < Value>hdfs-master,hdfs-slave1,hdfs-slave2</value>    </property>       <property>          <name>hbase.master</name >          <value>192.168.3.10:60000</value>       </property>      <property>           <name>zookeeper.session.timeout</name>           <value>60000</value>       </property>      <property>           <name>hbase.zookeeper.property.clientPort</name>           <value>2222</value>       </property&gT;    </configuration> 

#vim regionservers (Add all Datanode host names here)
Hdfs-slave1
Hdfs-slave2
4. Distributing files to other Datanode nodes on the cluster
Scp-r/usr/local/hadoop/hbase [Email protected]:/usr/local/hadoop/
Scp-r/usr/local/hadoop/hbase [Email protected]:/usr/local/hadoop/
5. Start HBase in Namenode:
/usr/local/hadoop/hbase/bin/start-hbase.sh
View in Namenode with JPS command
[[email protected] soft]# JPS
10546 Jps
2282 Secondarynamenode
10040 Hquorumpeer
10124 Hmaster
2127 NameNode
2437 ResourceManager
On Datanode, use the JPS command to view
[Email protected] hadoop]# JPS
836 DataNode
3140 Hregionserver
3329 Jps
3028 Hquorumpeer
6. Test HBase functionality
HBase Shell
6.1 Displaying data tables and creating student tables (with Name and address fields)
HBase (main):015:0> list
TABLE
0 row (s) in 0.0220 seconds
= []
HBase (main):016:0> create ' student ', ' name ', ' address '
0 row (s) in 0.4350 seconds
= Hbase::table-student
6.2 Insert a record and insert only one column
HBase (main):017:0> put ' student ', ' 1 ', ' name ', ' Tom '
0 row (s) in 0.2500 seconds
6.3. Query a record based on row value
HBase (main):018:0> get ' student ', ' 1 '
COLUMN CELL
name:timestamp=1411002916692, Value=tom
1 row (s) in 0.0260 seconds
6.4. Insert a family address to the student's address cluster
HBase (main):019:0> put ' student ', ' 1 ', ' address:home ', ' Shenzhen Street '
0 row (s) in 0.0180 seconds
6.5 Check the student's home address
HBase (main):020:0> get ' student ', ' 1 ',{column=> ' address:home '}
COLUMN CELL
Address:home timestamp=1411003134400, Value=shenzhen Street
1 row (s) in 0.0250 seconds
6.6 Delete data table (need to disable ' table name first ')
HBase (Main):023:0> disable "student"
0 row (s) in 1.3480 seconds
HBase (Main):024:0> drop "student"
0 row (s) in 0.2060 seconds
HBase (main):025:0> list
TABLE
0 row (s) in 0.0210 seconds
= []
