[jira] [Created] (SOLR-6372) HdfsDirectoryFactory should use supplied Configuration for communicating with secure kerberos

Gregory Chanan created SOLR-6372:
------------------------------------

             Summary: HdfsDirectoryFactory should use supplied Configuration for communicating with secure kerberos
                 Key: SOLR-6372
                 URL: https://issues.apache.org/jira/browse/SOLR-6372
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.4, 5.0
            Reporter: Gregory Chanan


When setting the UserGroupInformation's Configuration, HdfsDirectorFactory creates a new Configuration, see here:
https://github.com/apache/lucene-solr/blob/44f0dd7599901ba4d3625b5da8b998858e198d67/solr/core/src/java/org/apache/solr/core/HdfsDirectoryFactory.java#L306

The issue with this is when it's used to set the UserGroupInformation configuration, it can overwrite any existing configuration, which may have other (server) settings like kerberos rules. Ideally there would be separate client/servers interfaces so this wouldn't be an issue.  But lacking that, using the passed in Configuration allows the user to always specify all necessary settings.
