attilapiros opened a new pull request #24697: [MINOR][Core] Disable by default fetching of disk persisted RDD blocks via external shuffle service
URL: https://github.com/apache/spark/pull/24697
 
 
   ## What changes were proposed in this pull request?
   
   In the PR the config `spark.shuffle.service.fetch.rdd.enabled` default is changed to **false** to avoid breaking any compatibility with older external shuffle service installations. As external shuffle service is deployed separately and disk persisted RDD block fetching had even introduced new network messages (`RemoveBlocks` and `BlocksRemoved`) and changed the behaviour of the already existing fetching: extended it for RDD blocks.
   
   ## How was this patch tested?
   
   With existing unit tests.
