Subject [jira] [Created] (CARBONDATA-459) Block distribution is wrong in case of dynamic allocation=true
Date Mon, 28 Nov 2016 10:26:59 GMT
Manish Gupta created CARBONDATA-459:
---------------------------------------

             Summary: Block distribution is wrong in case of dynamic allocation=true
                 Key: CARBONDATA-459
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-459
             Project: CarbonData
          Issue Type: Bug
            Reporter: Manish Gupta
            Assignee: Manish Gupta
            Priority: Minor
             Fix For: 0.2.0-incubating


In case when dynamic allocation is true and configured max executors are more than the initial
executors then carbon is not able to request the max number of executors configured. Due to
this resources are getting under utilized and case when number of blocks increases, the distribution
of blocks is limited to the number of nodes and the number of tasks launched are less. This
leads to under utilization of resources and hence impacts the query and load performance.
