> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Reporter: Vinayakumar B
> Assignee: Vinayakumar B
> Attachments: HDFS-11738-01.patch, HDFS-11738-02.patch,

>
> Scenario :
> Same as HDFS-11708.
> During Hedge read,
> 1. First two locations fails to read the data in hedged mode.
> 2. chooseData refetches locations and adds a future to read from DN3.
> 3. after adding future to DN3, main thread goes for refetching locations in
> loop and stucks there till all 3 retries to fetch locations exhausted, which
> consumes ~20 seconds with exponential retry time.
