--------------------------------------
Summary: Pro-active block replenishment in case of node/executor
failures
Key: SPARK-15355
URL: https://issues.apache.org/jira/browse/SPARK-15355
Project: Spark
Issue Type: Sub-task
Components: Block Manager, Spark Core
Reporter: Shubham Chopra
Spark currently does not replenish lost replicas. For resiliency and high
availability, BlockManagerMasterEndpoint can proactively verify whether all
cached RDDs have enough replicas, and replenish them, in case they don’t.
