[jira] [Commented] (AMBARI-2941) Ambari server gets auth exception
while getting JMX metrics from namenode in secure cluster.
[ https://issues.apache.org/jira/browse/AMBARI-2941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13744256#comment-13744256 ]
Nate Cole commented on AMBARI-2941:
-----------------------------------
* This paradigm (DCL) is no longer necessary:
{noformat}
+ if (sslSocketFactory == null) {
+ synchronized (this) {
+ if (sslSocketFactory == null) {
{noformat}
You already made sslSocketFactory volatile, and the compiler is smarter than it used to be, making the DCL unnecessary. You should be able to single-check it.
