> Remove synchronization for UGI.getCurrentUser

>
> Key: HADOOP-9749
> URL: https://issues.apache.org/jira/browse/HADOOP-9749
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: security
> Affects Versions: 0.23.0, 2.0.0-alpha, 3.0.0-alpha1
> Reporter: Daryn Sharp
> Assignee: Daryn Sharp
> Priority: Critical
> Attachments: HADOOP-9749.branch-2.patch, HADOOP-9749.trunk.patch
>
>
> HADOOP-7854 added synchronization to {{getCurrentUser}} due to {{ConcurrentModificationExceptions}}. This degrades NN call handler performance.
> The problem was not well understood at the time, but it's caused by a collision between relogin and {{getCurrentUser}} due to a bug in {{Krb5LoginModule}}. Avoiding the collision will allow removal of the synchronization.
