-----------------------------------------
Summary: 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
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.
