> Maintain Short-Circuit Read Statistics
> --------------------------------------
>
> Key: HDFS-11789
> URL: https://issues.apache.org/jira/browse/HDFS-11789
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs-client
> Reporter: Hanisha Koneru
> Assignee: Hanisha Koneru
> Attachments: HDFS-11789.001.patch, HDFS-11789.002.patch
>
>
> If a disk or controller hardware is faulty then short-circuit read requests
> can stall indefinitely while reading from the file descriptor. Currently
> there is no way to detect when short-circuit read requests are slow or
> blocked.
> This Jira proposes that each BlockReaderLocal maintain read statistics while
> it is active by measuring the time taken for a pre-determined fraction of
> read requests. These per-reader stats can be aggregated into global stats
> when the reader is closed. The aggregate statistics can be exposed via JMX.
