Subject [jira] [Commented] (YARN-649) Make container logs available over HTTP in plain text
Date Wed, 21 Aug 2013 21:40:52 GMT

    [ https://issues.apache.org/jira/browse/YARN-649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13746880#comment-13746880
] 

Sandy Ryza commented on YARN-649:
---------------------------------

Uploading a new patch that
* Puts IOUtils.skipFully(logByteStream, start) back in.  My mistake.
* Changes the annotation to Unstable and includes documentation on how long logs will be available.
* Removes the mortbay log and throws a YarnException on the URISyntaxException

I manually verified that the buffering works by creating a log file larger than the NodeManager
memory, retrieving it with the API, and observing that the NodeManager did not fall over.

> 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.
