We have some data that we are exporting from our HDFS cluster to S3 with
some help from Spark. The final RDD command we run is:
csvData.saveAsTextFile("s3n://data/mess/2014/11/dump-oct-30-to-nov-5-gzip",
classOf[GzipCodec])
We have our 'spark.local.dir' set to our large ephemeral partition on
each slave (on EC2), but with compression on an intermediate format
seems to be written to /tmp/hadoop-root/s3. Is this a bug in Spark or
are we missing a configuration property?
It's a problem for us because the root disks on EC2 xls are small (~ 5GB).
