> Provide bytes-read-by-network-distance metrics at FileSystem.Statistics level
> -----------------------------------------------------------------------------
>
> Key: HDFS-9579
> URL: https://issues.apache.org/jira/browse/HDFS-9579
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Ming Ma
> Assignee: Ming Ma
> Attachments: HDFS-9579.patch
>
>
> For cross DC distcp or other applications, it becomes useful to have insight
> as to the traffic volume for each network distance to distinguish cross-DC
> traffic, local-DC-remote-rack, etc.
> FileSystem's existing {{bytesRead}} metrics tracks all the bytes read. To
> provide additional metrics for each network distance, we can add additional
> metrics to FileSystem level and have {{DFSInputStream}} update the value
> based on the network distance between client and the datanode.
> {{DFSClient}} will resolve client machine's network location as part of its
> initialization. It doesn't need to resolve datanode's network location for
> each read as {{DatanodeInfo}} already has the info.
> There are existing HDFS specific metrics such as {{ReadStatistics}} and
> {{DFSHedgedReadMetrics}}. But these metrics are only accessible via
> {{DFSClient}} or {{DFSInputStream}}. Not something that application framework
> such as MR and Tez can get to. That is the benefit of storing these new
> metrics in FileSystem.Statistics.
> This jira only includes metrics generation by HDFS. The consumption of these
> metrics at MR and Tez will be tracked by separated jiras.
> We can add similar metrics for HDFS write scenario later if it is necessary.
