> DFSInputStream retries too many times for new block locations

> Key: HDFS-927
> URL: https://issues.apache.org/jira/browse/HDFS-927
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs client
> Affects Versions: 0.21.0, 0.22.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Critical
> Attachments: hdfs-927.txt
>
>
> I think this is a regression caused by HDFS-127 -- DFSInputStream is supposed
> to only go back to the NN max.block.acquires times, but in trunk it goes back
> twice as many - the default is 3, but I am counting 7 calls to
> getBlockLocations before an exception is thrown.
