Hi All,

We are enabling hbase hook in apache atlas 2.2.0 , we followed below steps ,

https://atlas.apache.org/2.0.0/Hook-HBase.html

After that , when we start to start hbase , failing with below error.

Hello @Venkatd

Thanks for using Cloudera Community. This is an Older Post, yet I am sharing a review for fellow Community Users.

Based on the Post, the Service is affected owing to "org.apache.atlas.hbase.hook.HBaseAtlasCoprocessor" issues. A Quick Solution is to use "hbase.coprocessor.abortonerror" as "false" to avoid any Co-Processor failure cause Master/RegionServer startup failure.

Typically, Such issues are caused by few factors as shared below:
1. Missing "atlas.application.properties" from Atlas Configuration Directory in HBase Configuration Directory "/etc/hbase/conf".
2. The HBase-Atlas Hook being disabled.
3. Ensure "org.apache.atlas.hbase.hook.HBaseAtlasCoprocessor" is present in the Co-Processor Classes ("hbase.coprocessor.<master|region>.classes").

The Missing "atlas.application.properties" file is the Most-Likely Cause.

Hello @Venkatd

Since this is an Old Post & we have shared a few Action Plan with missing "atlas.application.properties" from Atlas Configuration Directory in HBase Configuration Directory "/etc/hbase/conf" being the Most-Likely reason for the concerned failure along with Steps to mitigate the HMaster/RegionServer failure (By setting "hbase.coprocessor.abortonerror" as "false") to avoid any Co-Processor failure cause Master/RegionServer startup failure, We shall mark the Post as Solved now.

Thank You for using Cloudera Community.
