Subject ConcurrentModificationException
Date Tue, 12 Dec 2017 07:29:58 GMT
We found this error when we read kafka data using storm:
java.util.ConcurrentModificationException         at java.util.LinkedHashMap$LinkedHashIterator.nextNode(LinkedHashMap.java:719)
        at java.util.LinkedHashMap$LinkedKeyIterator.next(LinkedHashMap.java:742)        
at java.util.AbstractCollection.addAll(AbstractCollection.java:343)May I ask this to fix the
program by ourselves? What code do we need to modify?Thanks!
