Date Fri, 24 Oct 2014 19:18:34 GMT

]

Karthik Kambatla updated YARN-2183:
-----------------------------------
    Attachment: on-demand-cleaner.patch

Here is a patch that applies on the v6, that relies on CleanerTask#run to ensure multiple
cleaner-tasks don't run concurrently. [~sjlee0], can you check if this makes any sense?
