> Remove duplicate locks in NetworkTopology
> -----------------------------------------
>
> Key: HADOOP-18236
> URL: https://issues.apache.org/jira/browse/HADOOP-18236
> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: ZanderXu
> Assignee: ZanderXu
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> During reading the hadoop NetworkTopology.java, I suspect there is a
> duplicate lock.
> chooseRandom(line 532), and code is:
> {code:java}
> final int availableNodes;
> if (excludedScope == null) {
> availableNodes = countNumOfAvailableNodes(scope, excludedNodes);
> } else {
> netlock.readLock().lock();
> try {
> availableNodes = countNumOfAvailableNodes(scope, excludedNodes) -
> countNumOfAvailableNodes(excludedScope, excludedNodes);
> } finally {
> netlock.readLock().unlock();
> }
> } {code}
> All the places where called `chooseRandom` have the global read lock, so the
> internal read lock is duplicated.
