> Set ratis protocol does not generate mlog, so that can not parse the
> specified metadata file.
> Step 1: Modify SchemaRegion consensus protocol type in
> iotdb-confignode.properties.
> {code:java}
> schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus{code}
> Step 2: Start 3C3D
> Step 3: Execute SQL in CLI
> But can't generate mLog. Like this:
> !image-2022-09-27-13-54-56-701.png|width=528,height=134!
> Modify parameters in iotdb-confignode.properties:
> {code:java}
> schema_region_consensus_protocol_class=org.apache.iotdb.consensus.standalone.StandAloneConsensus
> {code}
> Like this can generate mlog
> !image-2022-09-27-15-03-41-005.png|width=530,height=237!
> Therefore, it is necessary to add a description in the MLogParser-Tool module
> of the UserGuide.
