Subject [jira] [Commented] (YARN-649) Make container logs available over HTTP in plain text
Date Wed, 10 Jul 2013 17:29:49 GMT

    [ https://issues.apache.org/jira/browse/YARN-649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13704787#comment-13704787
] 

Alejandro Abdelnur commented on YARN-649:
-----------------------------------------

The streaming is done using an StreamingOutput instance in the NMWebServices, that is a javax.ws
interface. The buffer is defined there. While we are at this, [~sandyr], would you lower the
buffer size to 8K, no need to use 64K. if the underlying streams impls have larger buffers
the only additional cost is extra looping.

On YARN-911, you are right, i've missed that {{pre._(new String(cbuf, 0, len));}} is actually
streaming out. closing YARN-911 as invalid.

[~sandyr], would you address [~vinodkv] concerns?

> It would be good to make container logs available over the REST API for MAPREDUCE-4362
and so that they can be accessed programatically in general.
