Here is snippet from test output without fix:

> URL: https://issues.apache.org/jira/browse/HBASE-21466
> Project: HBase
> Issue Type: Bug
> Reporter: Ted Yu
> Assignee: Ted Yu
> Priority: Major
> Attachments: 21466.v1.txt
>
>
> In WALProcedureStore ctor , the fs field is initialized this way:
> {code}
> this.fs = walDir.getFileSystem(conf);
> {code}
> However, when wal.dir is not under rootdir, the above would return wrong
> FileSystem.
> In the modified TestMasterProcedureEvents, without fix, the master wouldn't
> initialize.
