Vlad Rozov created APEXCORE-638:
-----------------------------------
Summary: FSEventRecorder logs misleading ERROR messages
Key: APEXCORE-638
URL: https://issues.apache.org/jira/browse/APEXCORE-638
Project: Apache Apex Core
Issue Type: Bug
Reporter: Vlad Rozov
Priority: Minor
Every time Application Master records StramEvent, it logs ERROR message in case
web socket receiver is not properly configured. The error is misleading as it
does not cause any problem and the exception is swallowed. There should be only
one WARN message, when websocket tries to connect and fails and one INFO
message, when websocket is able to re-connect:
