> As a part of HBASE-18533, the Jenkins report said that TestFileIOEngine
> failed. I investigated and noticed that there are two cases where this test
> is flaky:
> len = 0 and offset 0; it will fail for
> https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/bucket/FileIOEngine.java#L198
> will pass in -1 for offset which is invalid.
> len = 0 and i = 13; it will try to specify an offset of the totalCapacity
> which is not allowed.
>
> This patch fixes this test.
