> HostsFileReader#getHostDetails is very expensive on large clusters

> Key: HADOOP-14412
> URL: https://issues.apache.org/jira/browse/HADOOP-14412
> Project: Hadoop Common
> Issue Type: Bug
> Components: util
> Affects Versions: 2.8.0
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Attachments: HADOOP-14412.001.patch, HADOOP-14412.002.patch,
> HADOOP-14412-branch-2.001.patch, HADOOP-14412-branch-2.002.patch,
> HADOOP-14412-branch-2.8.002.patch
>
>
> After upgrading one of our large clusters to 2.8 we noticed many IPC server
> threads of the resourcemanager spending time in NodesListManager#isValidNode
> which in turn was calling HostsFileReader#getHostDetails. The latter is
> creating complete copies of the include and exclude sets for every node
> heartbeat, and these sets are not small due to the size of the cluster.
> These copies are causing multiple resizes of the underlying HashSets being
> filled and creating lots of garbage.
