lhaiesp opened a new pull request #1441: URL: https://github.com/apache/samza/pull/1441
Problem: If YARN does not immediately allocate resources for a container and host affinity is disabled for the job, then the container allocator will spam the logs with messages about the request, even if the request is considered expired. This is because the allocator loops over the pending requests to check if they have been allocated, but there is no delay between loop iterations, so it might just keep checking the same pending request over and over as fast as possible. A metric is also incremented in this flow, so that metric is extremely high, which is probably not the intention. Changes: Avoid infinite loop by breaking the loop if host affinity is disabled Tests: new unit test API changes: N/A Usage instructions: N/A Upgrade instructions: None ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
