---------------------------------

             Summary: Refactor WALProcedureStore and add more comments for better understanding the implementation
                 Key: HBASE-21250
                 URL: https://issues.apache.org/jira/browse/HBASE-21250
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang
             Fix For: 3.0.0, 2.2.0


The implementation is complicated and lack of comments to say how it works.

{code}
/**
 * WAL implementation of the ProcedureStore.
 * @see ProcedureWALPrettyPrinter for printing content of a single WAL.
 * @see #main(String[]) to parse a directory of MasterWALProcs.
 */
{code}

I think at least we can move sub classes to separated files to make the class smaller, and add more comments to describe what is going on here.
