Subject [jira] Commented: (HADOOP-6728) Overhaul metrics framework
Date Sat, 18 Sep 2010 03:59:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12910892#action_12910892

Allen Wittenauer commented on HADOOP-6728:

>Why not web service REST api?

Because custom, proprietary interfaces are evil and are a calling card of NIH?

I'd rather change the things we are looking at by changing a few parameters in our JMX clients
than deal with Yet Another REST  Interface.  Screw backward compatibility if it means sticking
with something standard.

> Per discussions with Arun, Chris, Hong and Rajiv, et al, we concluded that the current
metrics framework needs an overhaul to:
> * Allow multiple plugins for different monitoring systems simultaneously (see also: HADOOP-6508).
> * Refresh metrics plugin config without server restart.
> ** Including filtering of metrics per plugin.
> * Support metrics schema for plugins.
> The jira will be resolved when core hadoop components (hdfs, mapreduce) are updated to
use the new framework . Updates to external components that use the existing metrics framework
will be tracked by different issues.
