Hadoop configuration was introduced in the previous blog, where hbase and hive are configured directly.
Master node: lab201,slave node: lab201,lab202,lab203
All three nodes perform the following operations (take the master node as an example)
[root@lab201] # tar xf hbase-0.90.6-cdh4u6.tar.gz-C / usr/local/
[root@lab201 local] # ln-sv hbase-0.90.6-cdh4u6/ hbase
[root@lab202 ~] # vim / etc/profile.d/hbase.sh
HBASE_HOME=/usr/local/hbase
PATH=$HBASE_HOME/bin:$PATH
Export HBASE_HOME PATH
[root@lab201] # chown-R hduser.hduser / usr/local/hbase/
Master node configuration:
[root@lab201 conf] # vim hbase-site.xml
Hbase.rootdir hdfs://lab201:8020/hbase hbase.cluster.distributed true hbase.zookeeper.quorum lab201,lab202,lab203 hbase.zookeeper.property.clientPort 2222
[hduser@lab201 ~] $vim / usr/local/hbase/conf/regionservers
Lab201
Lab202
Lab203
[root@lab201 ~] # scp / usr/local/hbase/conf/hbase-site.xml / usr/local/hbase/conf/regionservers hduser@lab202:/usr/local/hbase/conf/
[root@lab201 ~] # scp / usr/local/hbase/conf/hbase-site.xml / usr/local/hbase/conf/regionservers hduser@lab203:/usr/local/hbase/conf/
[hduser@lab201 ~] $start-hbase.sh to view the processes started on the primary node
12717 HRegionServer
13533 HQuorumPeer
13600 HMaster
[hduser@lab202 conf] $jps to view processes started from the node
4025 HRegionServer
3937 HQuorumPeer
Verify that it is normal:
Web accesses port 60010 of master and port 60030 of slave to see if it can be accessed properly.
Use shell to connect to Hbase for functional testing:
[hduser@lab201 ~] $hbase shell
Hbase (main): 003test', 0 > create 'test',' cf'0 row (s) in 1.2200 secondshbase (main): 003VOO > list 'table'test1 row (s) in 0.0550 secondshbase (main): 004Rich 0 > put' test', 'row1',' cf:a', 'value1'0 row (s) in 0.0560 secondshbase (main): 007V0 > scan' test'ROW COLUMN+CELLrow1 column=cf:a, timestamp=1288380727188, value=value11 row (s) in 0.0590 seconds
Hive configuration:
Do the following on all three nodes (take the master node as an example)
[root@lab201] # tar xf hive-0.7.1-cdh4u6.tar.gz-C / usr/local/
[root@lab201 ~] # ln-sv hive-0.7.1-cdh4u6/ hive
[root@lab201] # chown-R hduser.hduser / usr/local/hive/
[root@lab201 ~] # vim / etc/profile.d/hive.sh
HIVE_HOME=/usr/local/hive
PATH=$HIVE_HOME/bin:$PATH
Export HIVE_HOME PATH
Master does the following
[root@lab201 conf] # cp hive-default.xml hive-site.xml
[root@lab201 conf] # cp hive-env.sh.template hive-env.sh
[root@lab201 conf] # scp hive-site.xml hive-env.sh root@lab2:/usr/local/hive/conf/
[root@lab201 conf] # scp hive-site.xml hive-env.sh root@lab3:/usr/local/hive/conf/
Start hive and test:
[hduser@lab203 ~] $hive
Hive > create TABLE pokes (id INT, name string); hive > SHOW TABLES;hive > select * from pokes;hive > drop table pokes
Note: this is only the most basic configuration that allows hbase and hive to run. For more functionality and usage, please refer to the official documentation. The hadoop components used in this lab are downloaded from http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDHTarballs/3.25.2013/CDH3-Downloadable-Tarballs/CDH3-Downloadable-Tarballs.html, so all components have solved compatibility issues. The actual configuration process may need to be adjusted in some places according to the software version and specific conditions.
