Subject [jira] [Commented] (HADOOP-11815) AM JVM hungs after job unregister and finished
Date Wed, 08 Apr 2015 22:52:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11815?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14486255#comment-14486255

Haohui Mai commented on HADOOP-11815:
-------------------------------------

The general approach looks good to me. A cleaner way is to store {{SignerSecretProvider}}
in a final field in {{HttpServer2}} and to call {{destroy()}} on the field.
