[jira] [Commented] (PHOENIX-5572) httpclient NoClassDefFoundError due to old httpcore version

    [ https://issues.apache.org/jira/browse/PHOENIX-5572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16975398#comment-16975398 ]

---------------------------------------

Just a question/idea from the peanut gallery. Would something like https://maven.apache.org/enforcer/enforcer-rules/dependencyConvergence.html help here to avoid issues like this in the future?

> Phoenix pulls in httpclient 4.5.2  via hadoop3.
> It also depends on httpcore 4.1.3 via tephra.
> Unfortunately, httpclient 4.5.2 is not compatible with httpcore 4.1.3, and trying to use it results in
> _java.lang.NoClassDefFoundError: org/apache/phoenix/shaded/org/apache/http/Consts_
> This was found during testing the spark connector on a cluster with KMS.
