> Key: HBASE-11586
> URL: https://issues.apache.org/jira/browse/HBASE-11586
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.4
> Reporter: Andrew Purtell
> Assignee: Lars Hofhansl
> Fix For: 0.99.0, 0.98.5, 2.0.0
>
> Attachments: HBASE-11586.patch, HBASE-11586.patch
>
>
> HFileReaderV2 calls HFile#offerReadLatency and HFileWriterV2 calls
> HFile#offerWriteLatency but the samples are never drained. There are no
> callers of HFile#getReadLatenciesNanos, HFile#getWriteLatenciesNanos, and
> related. The three ArrayBlockingQueues we are using as sample buffers in
> HFile will fill quickly and are never drained.
> There are also no callers of HFile#getReadTimeMs or HFile#getWriteTimeMs, and
> related, so we are incrementing a set of AtomicLong counters that will never
> be read nor reset.
> We are calling System.nanoTime in block read and write paths twice but not
> utilizing the measurements.
> We should hook this code back up to metrics or remove it.
> We are also not using HFile#getChecksumFailuresCount anywhere but in some
> unit test code.
