Subject [jira] [Commented] (SPARK-6832) Handle partial reads in SparkR JVM to worker communication
Date Tue, 09 Aug 2016 18:29:20 GMT

    [ https://issues.apache.org/jira/browse/SPARK-6832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15413972#comment-15413972

Krishna Kalyan commented on SPARK-6832:
---------------------------------------

[~shivaram] 
I see that changes need to made in `R/pkg/R/deserialize.R` and specifically in the `readString`
function. However I dont understand how to go about making changes to enable partial reads.
I have gone through `https://stat.ethz.ch/R-manual/R-devel/library/base/html/readBin.html`.


Thanks,
Krishna

> After we move to use socket between R worker and JVM, it's possible that readBin() in
R will return partial results (for example, interrupted by signal).
