Subject [jira] [Commented] (HADOOP-13551) hook up AwsSdkMetrics to hadoop metrics
Date Fri, 24 Nov 2017 17:38:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16265456#comment-16265456
] 

Steve Loughran commented on HADOOP-13551:
-----------------------------------------

Looks like the http pool stats could be interesting: available count and time-to-acquire lease;
can identify undercapacity in connection pool before things fail (HADOOP-14621) or block (SPARK-22526)
