[jira] [Updated] (SPARK-2243) Support multiple SparkContexts in the
same JVM
[ https://issues.apache.org/jira/browse/SPARK-2243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Ash updated SPARK-2243:
------------------------------
Affects Version/s: 0.7.0
> Support multiple SparkContexts in the same JVM
> ----------------------------------------------
>
> Key: SPARK-2243
> URL: https://issues.apache.org/jira/browse/SPARK-2243
> Project: Spark
> Issue Type: New Feature
> Components: Block Manager, Spark Core
> Affects Versions: 0.7.0, 1.0.0, 1.1.0
> Reporter: Miguel Angel Fernandez Diaz
>
> We're developing a platform where we create several Spark contexts for carrying out different calculations. Is there any restriction when using several Spark contexts? We have two contexts, one for Spark calculations and another one for Spark Streaming jobs. The next error arises when we first execute a Spark calculation and, once the execution is finished, a Spark Streaming job is launched:
