> [SPS]: Limit the number of satisfyStoragePolicy items at Namenode

>
> Key: HDFS-11244
> URL: https://issues.apache.org/jira/browse/HDFS-11244
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode, namenode
> Reporter: Uma Maheswara Rao G
> Assignee: Uma Maheswara Rao G
>
> This JIRA is to provide a provision to limit the number storagePolisySatisfy
> pending queues. If we don't limit this number and if users keep calling more
> and more and if DNs are slow processing machines, then NN sides queues can
> grow up. So, it may be good to have an option to limit incoming requests for
> satisfyStoragePolicy. May be default 10K?
