Subject [jira] [Updated] (YARN-1564) add some basic workflow YARN services
Date Wed, 06 May 2015 14:32:02 GMT

     [ https://issues.apache.org/jira/browse/YARN-1564?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Loughran updated YARN-1564:
---------------------------------
    Attachment: YARN-1564-002.patch

Patch -002

Sync up with latest versions from slider, which are in production use. Primarily this enhances
the LongLivedProcess code to fix a startup race condition, be better at retrieving ongoing
stdout & stderr, and some other diagnostics.

Almost all the tests on process exec are skipped on windows as they have been pretty brittle
about the installed version of gnu/cygwin tools.

> I've been using some alternative composite services to help build workflows of process
execution in a YARN AM.
> They and their tests could be moved in YARN for the use by others -this would make it
easier to build aggregate services in an AM
