[jira] [Commented] (HIVE-3428) Fix log4j configuration errors when
running hive on hadoop23
[ https://issues.apache.org/jira/browse/HIVE-3428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13542594#comment-13542594 ]
Gunther Hagleitner commented on HIVE-3428:
------------------------------------------
Patch doesn't seem to provide configuration for hadoop.mr.rev=20S (hadoop 1-line). More importantly, if the only difference between the files is the Hadoop's deprecated EventCounter, it seems better to create a shim class for that. This way there's only one conf file and hive will pick the right file from the classpath at runtime.
