Matt Burgess commented on NIFI-2828:
------------------------------------
There are definitely issues with Hadoop versions between the
nifi-hadoop-libraries-nar (usually the parent), nifi-hdfs-processors,
nifi-hive-nar, HBase stuff, etc. For Hive it seems fairly picky about its
dependencies, so my suggested fix is to remove the dependency from the Hive NAR
on the Hadoop Libraries NAR, remove any "provided" scopes, and remove all
exclusions. This should involve complete regression testing of the Hive
components in NiFi.

> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Joey Frazee
>
> SelectHiveQL and PutHiveQL don't currently work with HTTP transport. There
> appears to be a class loader problem resulting in
> java.lang.NoClassDefFoundError: Could not initialize class
> org.apache.http.conn.ssl.SSLConnectionSocketFactory.
> This looks like a conflict with the Apache commons httpclient version in
> hadoop-common. Removing the hadoop-libraries .nar dependency and provided
> scope for hadoop-common appears to fix the issue, but I haven't done any
> rigorous testing so I'm not sure if there are other consequences or not.
