Subject [jira] [Updated] (YARN-1643) Make ContainersMonitor can support change monitoring size of an allocated container in NM side
Date Mon, 06 Jul 2015 22:26:04 GMT

     [ https://issues.apache.org/jira/browse/YARN-1643?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

MENG DING updated YARN-1643:
----------------------------
    Attachment: YARN-1643.2.patch

Attach patch for {{ContainersMonitorImpl}} for review.

Currently the {{ContainersMonitorImpl}} starts up one monitoring thread, and by default checks
started and stopped containers every 3 seconds.

For resized containers, we  cannot use the same logic as the delay is unacceptable.

A wait/notify mechanism is implemented such that as soon as a {{CHANGE_MONITORING_CONTAINER_RESOURCE}}
event is received, the monitor cycle is immediately triggered.
