This article will give you a detailed explanation on how to install Hbase distributed. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

[hadoop@master conf] $pwd

/ home/hadoop/hbase/conf

[hadoop@master conf] $vim hbase-env.sh

[hadoop@master conf] $

Export HBASE_CLASSPATH=/home/hadoop/hadoop/conf

BASE_MANAGES_ZK=true

[hadoop@master conf] $vim hbase-site.xml

If you want to know where the default parameters are, you can

[hadoop@master hbase] $find. -name "* default*"

. / docs/hbase-default.xml

. / src/main/resources/hbase-default.xml

[hadoop@master hbase] $vim src/main/resources/hbase-default.xml

View

Hbase.rootdir

Hdfs://master:9000/hbase

Hbase.cluster.distributed

True

Copy the driver because you want to support hadoop

[hadoop@master lib] $ll hadoop-core-1.0.4.jar

-rw-r--r-- 1 hadoop hadoop 3929148 2014-01-11 hadoop-core-1.0.4.jar

At this time, it was found that it was hadoop 1.0.4, and we used 1.2.1.

This jar can be deleted and copied. Come here.

[hadoop@master lib] $mv hadoop-core-1.0.4.jar hadoop-core-1.0.4.sav

[hadoop@master lib] $cp / home/hadoop/hadoop/hadoop-core-1.2.1.jar.

[hadoop@master lib] $ll hadoop-core-1.

Hadoop-core-1.0.4.sav hadoop-core-1.2.1.jar

Pseudo-distributed ok here

[hadoop@master conf] $start-hbase.sh

The authenticity of host 'localhost (127.0.0.1)' can't be established.

RSA key fingerprint is 6d:ef:a5:75:27:1d:7f:60:eb:ef:bc:dc:7c:4d:f7:a4.

Are you sure you want to continue connecting (yes/no)? Yes

Localhost: Warning: Permanently added 'localhost' (RSA) to the list of known hosts.

Because the cluster has only one thing, like ID.

[hadoop@master ~] $stop-hbase.sh

Stopping hbase.

Localhost: stopping zookeeper.

[hadoop@master ~] $hadoop fs-rmr / hbase
