-------------------------------------------
Thank you very much for the speedy fix!
> binaryRecords replicates records in scala API
> ---------------------------------------------
>
> Key: SPARK-19646
> URL: https://issues.apache.org/jira/browse/SPARK-19646
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.0.0, 2.1.0
> Reporter: BahaaEddin AlAila
> Assignee: Sean Owen
>
> The scala sc.binaryRecords replicates one record for the entire set.
> for example, I am trying to load the cifar binary data where in a big binary
> file, each 3073 represents a 32x32x3 bytes image with 1 byte for the label
> label. The file resides on my local filesystem.
> .take(5) returns 5 records all the same, .collect() returns 10,000 records
> all the same.
> What is puzzling is that the pyspark one works perfectly even though
> underneath it is calling the scala implementation.
> I have tested this on 2.1.0 and 2.0.0
