Rick Kellogg updated STORM-882:
-------------------------------
Component/s: storm-core
> Dist Cache: Have HDFS blob store download starting at a random block
> --------------------------------------------------------------------
>
> Key: STORM-882
> URL: https://issues.apache.org/jira/browse/STORM-882
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Reporter: Robert Joseph Evans
>
> To reduce the possibility of overloading a datanode when downloading large
> dist cache items we should start downloading the blob at a random block, and
> then loop back to the beginning of the file to finish. STORM-881 provides
> randomizing the order of the files downloaded, but on an update of a large
> blob this may become important.
