Description

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.

schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus

Step 2: Start 3C3D
Step 3: Execute SQL in CLI
But can't generate mLog.   Like this:

Modify parameters in iotdb-confignode.properties:

schema_region_consensus_protocol_class=org.apache.iotdb.consensus.standalone.StandAloneConsensus 

Like this can generate mlog

Therefore, it is necessary to add a description in the MLogParser-Tool module of the UserGuide.
