[HBASE-27702] Remove 'hbase.regionserver.hlog.writer.impl' config

• Type: Task
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.6.0, 3.0.0-alpha-4
• Component/s: wal
• Hadoop Flags: Reviewed

Release Note

Changed the configuration names to 'hbase.regionserver.wal.writer.impl' and 'hbase.regionserver.wal.async.writer.impl', which are mainly used for unit testing. End users should not use them.

Removed 'SecureProtobufLogWriter' and 'SecureAsyncProtobufLogWriter'. You can now use ProtobufLogWriter and AsyncProtobufLogWriter to write encrypted data directly. Since the configuration names have changed, there will be no problems if users’ old configuration files contain SecureProtobufLogWriter and SecureAsyncProtobufLogWriter, as they will never be loaded. But we still suggest that you remove these unused configurations from your configuration file.

Description

We do not support sequence file based WAL file any more, and we should also automatically choose SecureProtobufWALWriter if WAL entryption is enabled.

This is a follow up issue for HBASE-27632.
