[jira] [Created] (FLINK-7444) Make external calls non-blocking
Till Rohrmann created FLINK-7444:
------------------------------------
Summary: Make external calls non-blocking
Key: FLINK-7444
URL: https://issues.apache.org/jira/browse/FLINK-7444
Project: Flink
Issue Type: Bug
Components: Distributed Coordination
Affects Versions: 1.4.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
All external calls from a {{RpcEndpoint}} can be potentially blocking, e.g. calls to the {{FatalErrorHandler}}. Therefore, I propose to make all these calls coming from the {{RpcEndpoint's}} main thread non-blocking by running them in an {{Executor}}. That way the main thread will never be blocked.
