Hadoop Preparation: HBase Distributed installation Experience

When configuring Http://www.aliyun.com/zixun/aggregation/13713.html ">hbase, the first thing to consider is whether the HBase version matches the version of Hadoop you installed, which I

Blog has made it clear that the Hadoop version matches the HBase version, which is officially provided. The following experiment is that I did not refer to the version of the match to try to speculate on the method, there was an error.

Version Description:

hadoop1.1.2

hbase-0.94.7 (under Lib is Hadoop-core-1.0.4.jar)

JDK 1.6.0.24

First, see if the version of Hadoop and HBase match (there are errors, this step can be omitted)

If it does not match, you can replace the hadoop-core-* jar package under Hadoop with the hadoop-core-* jar package under Hbase/lib.

My Hadoop version is hadoop-1.1.2.

The hbase version of Lib is

So overwrite the jar package:

Ii. Modify the configuration of the Hbase-env.xml

A specifies the path of JDK and Hadoop under Conf

B Open HBase Management of zookeeper

Iii. Modification of Hbase-site.xml documents

A) Copy the Hbase-default.xml under hbase/src/main/resource/to the hbase/conf directory.

b Modify the root directory of HBase

Note: Root road strength is built on the HDFs

C Set the distributed configuration to true so that HBase understands that we are doing distributed.

D Modify the temporary directory of HBase

E Configure zookeeper to run the machine, typically set to a base

f) Configure zookeeper to store data in a directory

Iv. Modification of Conf/regionservers.xml

Remove localhost and add Slave1 Slave2

V. Distributing the configured HBase to Slave1 and slave2

A) scp-r hbase yao@slave1:/home/yao/

b) Scp-r HBase yao@slave2:/home/yao/

Six, configure Vi/etc/profile under the file (each machine needs to configure this):

A) export hbase_home=/home/yao/hbase

Export path= $PATH: $HBASE _home/bin

Vii. Start HBase

A) start-hbase.sh

Error: The report is version incompatible.

HBase Kai, multiple textual research turns out to be I think more:

Two questions: 1 There is no need to replace the jar packages in the hbase at first because they are compatible.

2 This error is my lazy factor, will hbase/src/main/resource/under the Hbase-default.xml copy to the hbase/conf directory, only configured I need, the other did not delete, I go, It hbase-default the wrong thing.

b The above two errors are changed and can be started.

SLAVE1:

Slave2:

Close hbase:

When this is closed, the ellipsis is always constant, which is probably a configuration error.

You can go to HBase's root directory log file to view the logs, find errors.
