Subject [jira] [Commented] (YARN-4053) Change the way metric values are stored in HBase Storage
Date Fri, 14 Aug 2015 23:48:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14697967#comment-14697967

Naganarasimha G R commented on YARN-4053:
-----------------------------------------

[~vrushalic] how about double ?
I feel it would be the better as it too takes the same size of long (8 bytes) and supports
decimals too ?

> Currently HBase implementation uses GenericObjectMapper to convert and store values in
backend HBase storage. This converts everything into a string representation(ASCII/UTF-8 encoded
byte array).
> While this is fine in most cases, it does not quite serve our use case for metrics. 
> So we need to decide how are we going to encode and decode metric values and store them
in HBase.
