[jira] [Commented] (YARN-649) Make container logs available over
HTTP in plain text
[ 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.
