----------------------------------
Summary: MetricFetcher Ask Timeout
Key: FLINK-5072
URL:
https://issues.apache.org/jira/browse/FLINK-5072 Project: Flink
Issue Type: Improvement
Reporter: Ufuk Celebi
Running a large scale test with 1.2-SNAPSHOT and heavy load on the TMs, I encountered a lot of ask timeouts for the metric fetcher:
{code}
akka.pattern.AskTimeoutException: Ask timed out on [Actor[akka.tcp://flink@10.240.0.52:34471/user/MetricQueryService_container_1479207428252_0014_01_000026]] after [10000 ms]

[~zentol] Does it make sense to investigate this further?
