[jira] [Created] (HBASE-19371) Running WALPerformanceEvaluation against asyncfswal throws exceptions

stack created HBASE-19371:
-----------------------------

             Summary: Running WALPerformanceEvaluation against asyncfswal throws exceptions
                 Key: HBASE-19371
                 URL: https://issues.apache.org/jira/browse/HBASE-19371
             Project: HBase
          Issue Type: Bug
            Reporter: stack


Was trying to do a perf eval on asyncfswal. I ran w/ these args:

 Performance counter stats for '/home/stack/hbase/bin/hbase --config /home/stack/conf_hbase org.apache.hadoop.hbase.wal.WALPerformanceEvaluation -path /user/stack/logs/ -verify -threads 25 -iterations 1000000 -keySize 50 -valueSize 100 -syncInterval 10':

The verify fails on all runs:

Exception in thread "main" java.lang.IllegalStateException: Counted=12390228, expected=25000000
  at org.apache.hadoop.hbase.wal.WALPerformanceEvaluation.run(WALPerformanceEvaluation.java:368)                                                                                                            at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:76)
  at org.apache.hadoop.hbase.wal.WALPerformanceEvaluation.innerMain(WALPerformanceEvaluation.java:597)                                                                                                      at org.apache.hadoop.hbase.wal.WALPerformanceEvaluation.main(WALPerformanceEvaluation.java:601)

I need to fix test or figure what is wrong in asyncfswal.

Also seeing these when I run w/ one thread only:

2017-11-28 21:25:49,952 WARN  [AsyncFSWAL-1-1] wal.AsyncFSWAL: RingBufferTruck with unexpected type: EMPTY

Log has a spew of them.

Has stuff like this too:

Starts out spewing EMPTY here:

This is tip of branch-2 minus the commit of the change to the ringbuffer (I'd not pulled in that change).

[~Apache9] in case you've seen it before else I'll dig in sir.
