Example 1 with LocalResource

use of org.apache.storm.localizer.LocalResource in project storm by apache.

the class UpdateBlobs method updateBlobsForTopology.

/**
     * Update each blob listed in the topology configuration if the latest version of the blob has not been downloaded.
     * 
     * @param conf
     * @param stormId

     * @throws IOException
