How to activate HBase Bulk Delete?

asif.mohammad — Fri, 16 Sep 2022 09:36:25 GMT

BulkDelete is not active by default and i'm trying to add to coprocessor region and restart, it didn't work. When i describe table i don't see bulk delete active

Here is my property value, i have appended BulkDelete property value to existing and restarted.

<name>hbase.coprocessor.region.classes</name>
<value>org.apache.hadoop.hbase.security.token.TokenProvider,org.apache.hadoop.hbase.security.access.AccessController,org.apache.hadoop.hbase.coprocessor.example.BulkDeleteEndpoint</value>

Any help would be apreciated.

Thanks,

Asif

Hi Asif,

Bulk Delete is an EndPoint coprocessor. Therefore, it is not related to a specific table, but more loaded for a RegionServer.

Because of that, you will not see it when you will describe a table from the shell because it is not attached to that specific table.

Only observers are attached to the tables and are displayed in the describe command.

HTH,

Jean-Marc

Thanks Jims.

Any easy way to test this bulkdelete as a admin?

Hi Asif,

You will need to do some code for that. Create a small table, put some data in it and call the bulk delete.

Here is an example:

https://github.com/apache/hbase/blob/master/hbase-examples/src/test/java/org/apache/hadoop/hbase/coprocessor/example/TestBulkDeleteProtocol.java

You might be able to re-use most of this code.
