Subject [jira] [Updated] (YARN-3102) Decommisioned Nodes not listed in Web UI
Date Fri, 08 Jan 2016 20:43:40 GMT

     [ https://issues.apache.org/jira/browse/YARN-3102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kuhu Shukla updated YARN-3102:
------------------------------
    Attachment: YARN-3102-v2.patch

Updating patch after addressing findbugs warning, failed test case and check-style issues.
Javadocs issue seems unrelated and could be connected to YARN-4567. 

Test failures in TestRMRestart were due to missing wait before checking the metrics since
now we transition the decommissioned RMNodes candidates instead of just populating the metric
count based on exclude list.

Test failure in TestFifoScheduler was not locally reproducible.
