Subject [jira] [Updated] (GIRAPH-838) setup time & total time counter also include time spent waiting for machines
Date Sun, 02 Feb 2014 19:02:09 GMT

     [ https://issues.apache.org/jira/browse/GIRAPH-838?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pavan Kumar updated GIRAPH-838:
-------------------------------

    Attachment: second.rtf
                first.rtf

Attached execution times for job launched first, [on 200 node cluster running for non-trivial
amount of time] making the job launched second wait for that time to acquire the resources
it needs.

As can be seen the setup time for second job does not include time to acquire machines, that
is separated into initialize time. same with total time.

> setup time & total time counter also include time spent waiting for machines

> Currently the setup time & total time counters also include time spent waiting to
acquire machines in the cluster. Because of this the total execution time shown on job page
is inaccurate. Total time should not include the time spend waiting for cluster resources.
