> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Ayush Saxena
> Assignee: Ayush Saxena
> Priority: Major
> Attachments: HDFS-14440-HDFS-13891-01.patch,

>
>
> In case of multiple destinations, We need to check if the file already exists
> in one of the subclusters for which we use the existing getBlockLocation()
> API which is by default a sequential Call,
> In an ideal scenario where the file needs to be created each subcluster shall
> be checked sequentially, this can be done concurrently to save time.
> In another case where the file is found and if the last block is null, we
> need to do getFileInfo to all the locations to get the location where the
> file exists. This also can be prevented by use of ConcurrentCall since we
> shall be having the remoteLocation to where the getBlockLocation returned a
> non null entry.
