-------------------------------------------
Summary: Time- and threshold-batched FetchFailure event
propagation to AM
Key: TEZ-4183
URL: https://issues.apache.org/jira/browse/TEZ-4183
Project: Apache Tez
Issue Type: Improvement
Reporter: Panagiotis Garefalakis
Fetcher currently sends failure events to AM as soon as they are discovered:
https://github.com/apache/tez/blob/354c2a4177fe8c3cf6b8a4c6009d4068a19d81f1/tez-runtime-library/src/main/java/org/apache/tez/runtime/library/common/shuffle/impl/ShuffleManager.java#L930
To reduce AM pressure we can: 1) Batch fetch failure events to be sent
periodically (every BATCH_WAIT) and 2) if we see disk errors more than a
Threshold send the message immediately to AM (instead of waiting)
