Ravindra Pesala commented on CARBONDATA-1624:
---------------------------------------------
Welcome to contribute.
We should not use the carbonproperties anymore for this dynamic cores as it
impacts other loads. First find the available cores which we can allocate for
loading per executor before submitting and pass the same information to carbon
in RDD compute.
> If SORT_SCOPE is non-GLOBAL_SORT with Spark, set
> 'carbon.number.of.cores.while.loading' dynamically as per the available
> executor cores

> URL: https://issues.apache.org/jira/browse/CARBONDATA-1624
> Project: CarbonData
> Issue Type: Improvement
> Components: data-load, spark-integration
> Affects Versions: 1.3.0
> Reporter: Zhichao Zhang
> Assignee: Zhichao Zhang
> Priority: Minor
>
> If we are using carbondata + spark to load data, we can set
> carbon.number.of.cores.while.loading to the number of executor cores.
> For example, when set the number of executor cores to 6, it shows that there
> are at
> least 6 cores per node for loading data, so we can set
> carbon.number.of.cores.while.loading to 6 automatically.
