James Clampffer updated HDFS-10951:
-----------------------------------
Parent Issue: HDFS-14032 (was: HDFS-8707)
> libhdfs++: FileHandle should handle DN failure internally
> ---------------------------------------------------------
>
> Key: HDFS-10951
> URL: https://issues.apache.org/jira/browse/HDFS-10951
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs-client
> Reporter: James Clampffer
> Assignee: James Clampffer
> Priority: Minor
>
> Currently if a read hits a bad DN it will add it to the DN exclusion set and
> return an error. It'd be nice if it'd exhaust attempts to all replica
> locations before returning an error so client applications don't have to
> attempt to figure out the difference between "File not found" and "DN not
> responsive, go try a different DN".
