I need help with hbase high availability for apache hadoop.

[#1]

I need help with hbase high availability for apache hadoop , as i have done HA successfully for HDFS but unable to do for hbase.

Also need help with hbase-site.xml

Kindly provide me steps to go for it.

Below are the following.

coresite.xml

<configuration>
<property>

You can refer to following guide to setup HA using Ambari

https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.1.0/bk_ambari-operations/content/hbase_high_ava...

I have to setup HA for hbase in apache hadoop , not using HDP and not using Ambari

[#4]

@ASIF Khan

Unfortunately you went the wrong road. Troubleshooting such an orthodox implementation becomes a nightmare, it advisable to use standard management tool like Ambari when implementing HDP clusters.

Folks here could easily guide you and locate the config files easily and hence help out.

I understand @Geoffrey Shelton Okot , but its client requirement and has to work accordingly. Ive already proposed Hortonworks and to implement it will take time, for now i have to enable HA for hbase in the current apache hadoop environment.

[#6 · Accepted solution]

Issue has been resolved as we have to enable Backup-Master for Hbase.
