Subject [jira] [Commented] (MAPREDUCE-5937) hadoop/mapred job -history <history_file> shows the counters twice in the output.

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15228050#comment-15228050

Akira AJISAKA commented on MAPREDUCE-5937:

bq. So do you think that instead of using what the current patch is doing, we should change
what the actual AbstractCounter#getGroupNames returns?
Yes. That way we can avoid duplicate entries for JSONHistoryViewerPrinter as well. The current
patch ignores all of the deprecated counter name.
