[jira] [Updated] (TEZ-4510) Performance counters

     [ https://issues.apache.org/jira/browse/TEZ-4510?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

László Bodor updated TEZ-4510:
------------------------------
    Description: We need to improve on counters that can help to decide what went wrong in case of performance degradation. Such counters are not necessarily and always helpful for a single instance of a query/dag, but instead when comparing different runs of the same query/dag.
