Subject [jira] [Commented] (HBASE-12894) Upgrade Jetty to 9.2.6
Date Wed, 12 Oct 2016 20:18:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15569761#comment-15569761
] 

stack commented on HBASE-12894:
-------------------------------

On Constants being local to REST, that is my mistake. I did not notice. Excuse my comment.

On jetty6 being in different package, yes, that makes us safe against old jetty6 at least.

You bring up a good point on the jersey and servlet versions. I took a look over at hadoop
and currently our versions are aligned, even on the hadoop3 alpha. Spark is on the servlet
and jersey version you move us to in this patch. We could exclude which would work for the
classpath we control. Any clash would be in the server and rest modules only. We have a switch
to disable webservice so could avoid trying to load these classes in problematic contexts.

Hmm. Anyone else have an opinion here? [~busbey] or [~enis]? My inclination is to commit this
patch and then file a follow-on issue whose subject is "How to deal with updated libraries
in hbase2". My thought is that we will have bigger issues than the two libs here.

> The Jetty component that is used for the HBase Stargate REST endpoint is version 6.1.26
and is fairly outdated. We recently had a customer inquire about enabling cross-origin resource
sharing (CORS) for the REST endpoint and found that this older version does not include the
necessary filter or configuration options, highlighted at: http://wiki.eclipse.org/Jetty/Feature/Cross_Origin_Filter
> The Jetty project has had significant updates through versions 7, 8 and 9, including
a transition to be an Eclipse subproject, so updating to the latest version may be non-trivial.
The last update to the Jetty component in https://issues.apache.org/jira/browse/HBASE-3377
was a minor version update and did not require significant work. This update will include
a package namespace update so there will likely be a larger number of required changes.
