> YARN ConcurrentModificationException When Refreshing Node Attributes
> --------------------------------------------------------------------
>
> Key: YARN-11838
> URL: https://issues.apache.org/jira/browse/YARN-11838
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodeattibute, yarn
> Affects Versions: 3.3.0, 3.2.1
> Reporter: Syed Shameerur Rahman
> Assignee: Syed Shameerur Rahman
> Priority: Major
> Labels: pull-request-available
>
> h2. The Problem Flow
> # A new node is being added to the cluster (NODE_ADDED event)
> # The CapacityScheduler calls addNode() method
> # This triggers refreshNodeAttributesToScheduler() in
> NodeAttributesManagerImpl
> # During this process, the code attempts to convert a HashMap to a string
> for logging
> # While iterating through the HashMap for string conversion, another thread
> modifies the same HashMap :
> https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/nodelabels/NodeAttributesManagerImpl.java#L748
> # This causes the ConcurrentModificationException
>
> {code:java}
