> HttpServer2 should switch to using the non-blocking SslSelectChannelConnector
> to prevent performance degradation when handling SSL connections

>
> Key: HADOOP-12765
> URL: https://issues.apache.org/jira/browse/HADOOP-12765
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 2.7.2, 2.6.3
> Reporter: Min Shen
> Assignee: Min Shen
> Attachments: HADOOP-12765-branch-2.patch, HADOOP-12765.001.patch,
> HADOOP-12765.001.patch, HADOOP-12765.002.patch, HADOOP-12765.003.patch,

>
> The current implementation uses the blocking SslSocketConnector which takes
> the default maxIdleTime as 200 seconds. We noticed in our cluster that when
> users use a custom client that accesses the WebHDFS REST APIs through https,
> it could block all the 250 handler threads in NN jetty server, causing severe
> performance degradation for accessing WebHDFS and NN web UI. Attached
> screenshots (blocking_1.png and blocking_2.png) illustrate that when using
> SslSocketConnector, the jetty handler threads are not released until the 200
> seconds maxIdleTime has passed. With sufficient number of SSL connections,
> this issue could render NN HttpServer to become entirely irresponsive.
> We propose to use the non-blocking SslSelectChannelConnector as a fix. We
> have deployed the attached patch within our cluster, and have seen
> significant improvement. The attached screenshot (unblocking.png) further
> illustrates the behavior of NN jetty server after switching to using
> SslSelectChannelConnector.
> The patch further disables SSLv3 protocol on server side to preserve the
> spirit of HADOOP-11260.
