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

org.apache.hadoop.hbase.wal.WALPerformanceEvaluation.innerMain(WALPerformanceEvaluation.java:597)

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:

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.
