You are right that the contract we have with the R->JVM API is that the run functions on the JVM running Spark. If we are going to enable multiple JVMs (or say multiple Spark contexts) then we will have to add some way to resolve which JVM to run. That might change the implementation but should not affect the API significantly I'd say (it would be something like passing a JVM id in the API). The second question is about whether we want to expose the more internal RBackend as a public API -- This is something we will have to discuss separately and I am not sure we are ready to make such an RPC API public yet. The remote backend change is still assuming the client and the server can change hand-in-hand. Making RBackend public will mean that the server side API is fixed. > Making JVM backend calling functions public > --- > > Key: SPARK-16581 > URL: https://issues.apache.org/jira/browse/SPARK-16581 > Project: Spark > Issue Type: Sub-task > Components: SparkR >Reporter: Shivaram Venkataraman > > As described in the design doc in SPARK-15799, to help packages that need to > call into the JVM, it will be good to expose some of the R -> JVM functions > we have. > As a part of this we could also rename, reformat the functions to make them > more user friendly. -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

Because we are not trying to build a library to generically work with JVM from R (like py4j) but only the JVM that Spark is running, via custom socket protocol; it might come a time we want to operate from a R shell while working with multiple JVM backends (or remote backends), or want to have more control over recycling the backend process not completely dissimilar to cleanup.jobj, etc. In addition to connect to a remote JVM, we might want to expose JVM side RBackend API to allow re-using an existing Spark JVM process (several Spark JIRAs in the past) for cases with Spark Job Server (persisted spark session), Apache Toree (incubating) / Livy (cross-languages support) (eg. https://issues.cloudera.org/projects/LIVY/issues/LIVY-194) Possibly some of these could change how callJMethod/invokeJava works, what parameters are required and so on. Of course, all of these could be very far off :) > Making JVM backend calling functions public > --- > > Key: SPARK-16581 > URL: https://issues.apache.org/jira/browse/SPARK-16581 > Project: Spark > Issue Type: Sub-task > Components: SparkR >Reporter: Shivaram Venkataraman > > As described in the design doc in SPARK-15799, to help packages that need to > call into the JVM, it will be good to expose some of the R -> JVM functions > we have. > As a part of this we could also rename, reformat the functions to make them > more user friendly. -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
