> Add a config option to make NetworkTopology#netLock fair

> Key: HADOOP-15486
> URL: https://issues.apache.org/jira/browse/HADOOP-15486
> Project: Hadoop Common
> Issue Type: Improvement
> Components: net

>
> Whenever a datanode is restarted, the registration call after the restart
> received by NameNode lands in {{NetworkTopology#add}} via
> {{DatanodeManager#registerDatanode}} requires write lock on
> {{NetworkTopology#netLock}}. This registration thread is getting starved by
> flood of {{FSNamesystem.getAdditionalDatanode}} calls, which are triggered by
> clients those who were writing to the restarted datanode.
> The registration call which is waiting for write lock on
> {{NetworkTopology#netLock}} is holding write lock on {{FSNamesystem#fsLock}},
> causing all the other RPC calls which require the lock on
> {{FSNamesystem#fsLock}} wait.
> We can introduce a config property to make {{NetworkTopology#netLock}} lock
> fair so that the registration thread will not starve.
