The issue https://issues.apache.org/jira/browse/SOLR-14660 is about moving the HDFS plugins out of core into a module. While a great thing, it still leaves quite a few Hadoop related dependencies in solr-core because Hadoop is not there only for HDFS; it's there for some exotic authentication & authorization plugins. In that JIRA issue I proposed that this module be "hadoop" and have any hadoop related plugins.
As a quick experiment, I commented out the hadoop-auth dependency and tried to compile to see what the compiler caught. It exposed the following two Solr plugins: * HadoopAuthPlugin * KerberosPlugin Are we okay with expanding the scope of SOLR-14660 to include these? Note that SOLR-14660 *might* result in 9.0 not including this module in the release distribution if we don't feel the module will be sufficiently ready to release. ~ David Smiley Apache Lucene/Solr Search Developer http://www.linkedin.com/in/davidwsmiley
