Project: Eagle
Issue Type: Bug
Affects Versions: v0.5.0
Reporter: Su Ralph
Assignee: Garrett Li
Priority: Critical
Fix For: v0.5.0
We are try to re-use eagle alert module as part our streaming processing core,
during test, we found below error.
6700 java.util.ConcurrentModificationException at
java.util.ArrayList$Itr.checkForComodification(ArrayList.java:901) at
java.util.ArrayList$Itr.next(ArrayList.java:851) at
org.apache.eagle.alert.engine.publisher.impl.AlertPublisherImpl.notifyAlert(AlertPublisherImpl.java:74)
It happens to be in AlertPublisherImpl, the metadata change is doing inplace
update, which cause the concurrency issue when the bolt is continuing ingest
data.
This exception should cause following data stream not able to be published.
Hence be blocker
