[jira] [Commented] (HCATALOG-53) HCatLoader, HCatStorer, HCatInputFormat, and HCatOutputFormat assume Hadoop running in secure mode

    [ https://issues.apache.org/jira/browse/HCATALOG-53?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13060143#comment-13060143 ] 

Ashutosh Chauhan commented on HCATALOG-53:
------------------------------------------

HiveConf reads hive-site.xml if found on its classpath when it is instantiated, so ideally all of these properties should come from external xml file, instead of setting and resetting them. For 0.1 timeline this patch is fine, but going forward we should get rid of setting any properties in the code and should read from external config xml files.

> If any of these are used when HCatalog is attached to a Hadoop cluster running in non-secure mode, they cause an NPE.  This is because they all assume that the security related configuration parameters are non-null.
