> Dist Cache: Basic Functionality
> -------------------------------
>
> Key: STORM-876
> URL: https://issues.apache.org/jira/browse/STORM-876
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans
> Attachments: DISTCACHE.md, DistributedCacheDesignDocument.pdf
>
>
> Basic functionality for the Dist Cache feature.
> As part of this a new API should be added to support uploading and
> downloading dist cache items. storm-core.ser, storm-conf.ser and storm.jar
> should be written into the blob store instead of residing locally. We need a
> default implementation of the blob store that does essentially what nimbus
> currently does and does not need anything extra. But having an HDFS backend
> too would be great for scalability and HA.
> The supervisor should provide a way to download and manage these blobs and
> provide a working directory for the worker process with symlinks to the
> blobs. It should also allow the blobs to be updated and switch the symlink
> atomically to point to the new blob once it is downloaded.
> All of this is already done by code internal to Yahoo! we are in the process
> of getting it ready to push back to open source shortly.
