Subject [jira] [Commented] (HDFS-10860) Switch HttpFS from Tomcat to Jetty
Date Tue, 31 Jan 2017 22:32:51 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15847657#comment-15847657

John Zhuge commented on HDFS-10860:

bq. Sorry should have asked this in the KMS jira. The new index.html page for loglevel/jmx/conf/logs
looks nice and handy. But how does the security work here? Have you tested this in a kerberized
environment? I tried locally in a pseudo-authenticated setup, it seems I can read/set everything
even without the user.name= param.

/conf, /jmx, /logLevel, and /stacks do report "Authentication required" when {{user.name}}
is not specified.

/logs do not require authentication. This does not seem right, will file another JIRA to follow

> The Tomcat 6 we are using will reach EOL at the end of 2017. While there are other good
options, I would propose switching to {{Jetty 9}} for the following reasons:
> * Easier migration. Both Tomcat and Jetty are based on {{Servlet Containers}}, so we
don't have to change client code that much. It would require more work to switch to {{JAX-RS}}.
> * Well established.
> * Good performance and scalability.
> Other alternatives:
> * Jersey + Grizzly
> * Tomcat 8
> Your opinions will be greatly appreciated.
