Subject [jira] [Resolved] (YARN-5235) Avoid re-creation of EventColumnNameConverter in HBaseTimelineWriterImpl#storeEvents
Date Thu, 16 Jun 2016 18:13:05 GMT

     [ https://issues.apache.org/jira/browse/YARN-5235?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joep Rottinghuis resolved YARN-5235.
------------------------------------
    Resolution: Won't Fix

Requires method signature changes in order to avoid light-weight object creation.
Let's tackle this if the converter ever does become a heavy-weight instance.

> As per discussion in YARN-5170 [~varun_saxena] noted:
> bq. In HBaseTimelineWriterImpl#storeEvents, we iterate over all events in a loop and
will be creating EventColumnNameConverter object each time. Although its not a very heavy
object right now, but can't we just create it once outside the loop ?
