> A more detailed flushOrSync Warn Log
> ------------------------------------
>
> Key: HDFS-17805
> URL: https://issues.apache.org/jira/browse/HDFS-17805
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode
> Reporter: Jiandan Yang
> Priority: Major
> Labels: pull-request-available
>
> When DataNode receives a request to flush or sync a block being written by a
> client , the method flushOrSync (boolean isSync) will be invoked.
> In this method, the duration of the whole process will be recorded, also the
> flush and sync time of streams will be summed and then marked as
> ‘flushTotalNanos’.
> If the duration of this ‘flush or sync’ process exceeds a certain threshold,
> a warn log would appear and tells the value of the duration and the
> ‘flushTotalNanos’, enabling us to pinpoint the slower part of the execution
> within the flushOrSync(boolean isSync) methods.
> The current log records the time for both flush and sync operations as a
> single metric called flushTotalNanos. However, if flushTotalNanos takes too
> long, users will not be able to further diagnose the issue in detail based on
> the log.
> I propose that the log separately display the durations of flush and sync
> operations, instead of combining them into flushTotalNanos. This would allow
> users to pinpoint issues more accurately.
