This article mainly introduces "how to deploy Hbase stand-alone and pseudo-distributed". In daily operation, I believe many people have doubts about how to deploy Hbase stand-alone and pseudo-distributed. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "how to deploy Hbase stand-alone and pseudo-distributed". Next, please follow the editor to study!

Compared with the official website

[hadoop@hadoop004 hbase-1.2.0-cdh6.12.0] $vim conf/hbase-site.xml hbase.unsafe.stream.capability.enforce true hbase.cluster.distributed true hbase.rootdir hdfs://hadoop004:9000/hbase hbase.zookeeper.quorum hadoop004:2181 [hadoop@hadoop004 hbase-1.2.0-cdh6.12.0] $vim conf/hbase-env.sh# add export HBASE_MANAGES_ZK=false

Start

[hadoop@hadoop004 hbase-1.2.0-cdh6.12.0] $bin/start-hbase.sh

Success!

Supplement

Pseudo-distributed installation is not plain sailing, but you must not panic when you encounter problems. Check the logs to troubleshoot the problems.

Problem recurrence

Start Hbase through the start-hbase.sh script, and then jps discovers that HMaster is not started

At this point, view the log output of HMaste

There is no useful information

[hadoop@hadoop004 hbase-1.2.0-cdh6.12.0] $tail-200 / home/hadoop/app/hbase-1.2.0-cdh6.12.0/logs/hbase-hadoop-master-hadoop004.log

The problem is that it appears in the red box.

Solution, in hbase-site.xml file

Got it!

In the beginning, the ZooKeeper that comes with Hbase is used by default when starting Hbase, but at this time, because my machine has already started ZooKeeper and occupied port 2181, HMaster also failed to start.

Solution

At this point, the study on "how to deploy Hbase stand-alone and pseudo-distributed" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
