> There is an understanding issue for a long time: https://issues.apache.org/jira/browse/SPARK-4105, without any checksum for the blocks, it's very hard for us to identify where is the bug came from.
> Shuffle blocks are compressed separate (have checksum in it), but broadcast blocks are compressed together, we should add checksum for each of separately.
