Subject [jira] Commented: (CHUKWA-260) unit conversions in Demux
Date Fri, 22 May 2009 18:22:45 GMT

    [ https://issues.apache.org/jira/browse/CHUKWA-260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712191#action_12712191

Jiaqi Tan commented on CHUKWA-260:
----------------------------------

Although this is sar-specific (or iostat) the Demux processor should read the column names,
parse them for units, and use that information as hints for converting the numerical into
the base units for the final information that's written to HDFS.
