Duo Zhang created HBASE-21250:
---------------------------------
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.
