Hi all,
TL;DR - is there a way to extract the source path from an RDD via the Scala
API?
I have sequence files on S3 that look something like this:
s3://data/customer=123/...
s3://data/customer=456/...
I am using Spark Dataframes to convert these sequence files to Parquet. As
part of the processing, I actually need to know the customer-id. I'm doing
something like this:
val rdd = sql.sparkContext.sequenceFile("s3://data/customer=*/*",
classOf[BytesWritable],
classOf[Text])
val rowRdd = rdd.map(x => convertTextRowToTypedRdd(x._2, schema, delimiter))
val dataFrame = sql.createDataFrame(rowRdd, schema)
What I am trying to figure out is how to get the customer-id, which is part
of the path. I am not sure if there's a way to extract the source path from
the resulting HadoopRDD. Do I need to create one RDD per customer to get
around this?
Thanks,
-Matt
