------------------------------------
Summary: Block Manager master and slave thread pools are unbounded
Key: SPARK-25181
URL: https://issues.apache.org/jira/browse/SPARK-25181
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.3.0
Reporter: Mukul Murthy
Currently, BlockManagerMasterEndpoint and BlockManagerSlaveEndpoint both have
thread pools with unbounded numbers of threads. In certain cases, this can lead
to driver OOM errors. We should add an upper bound on the number of threads in
these thread pools; this should not break any existing behavior because they
still have queues of size Integer.MAX_VALUE.
