Ted Yu commented on HBASE-10255:
--------------------------------
Should have provided more background on the perf test:
This was done on a 5-RS cluster where hadoop 2.2 was deployed.
Here was the command line used for both tests:
bin/hbase org.apache.hadoop.hbase.regionserver.wal.HLogPerformanceEvaluation
-path hdfs://hor12n22.gq1.ygridcore.net:8020/tmp -threads 10 -roll 1000 -verify
I obtained the first stat using 0.96
Then I switched jars recompiled with patch v2 and obtained the second set of
numbers.
> Remove dependency on LimitInputStream

> LimitInputStream has always been a @Beta API and beta apis aren't guaranteed
> to remain stable over such a long period (v12 to v15).
> LimitInputStream was copied from Guava v12
> The recommended replacement is to use ByteStreams#limit(java.io.InputStream,
> long) instead.
