Tried several times, it is slow same as before, I will let spark output
data to HDFS, then sync data to S3 as temporary solution.

Is there any way to write just the values ?

Jacek is correct for using org.apache.spark.ml.recommendation.ALSModel
If you are trying to save
org.apache.spark.mllib.recommendation.MatrixFactorizationModel, then it is
similar, but just a little different, see the example here
What about write.save(file)?
P.s. I'm new to Spark MLlib.

Are you trying to save predictions on a dataset to a file, or the model
produced after training with ALS?

Not quite sure if error is resolved. Upon further probing, the setting

false even though the webUI is indicating that it's been

Hi Ocatavian,
Just out of curiosity, did you try persisting your RDD in serialized format
MEMORY_AND_DISK_SER or MEMORY_ONLY_SER ??
i.e. changing your :
rdd.persist(MEMORY_AND_DISK)
to
rdd.persist(MEMORY_ONLY_SER)
Regards

I agree with Richard. It looks like the issue here is shuffling, and
shuffle data is always written to disk, so the issue is definitely not that
all the output of flatMap has to be stored in memory.
If at all possible, I'd first suggest upgrading to a new version of spark
-- even in 1.2, there
You could try rdd.persist(MEMORY_AND_DISK/DISK_ONLY).flatMap(...), I think
StorageLevel MEMORY_AND_DISK means spark will try to keep the data in
memory and if there isn't sufficient space then it will be shipped to the
disk.
Thanks
Best Regards

I was tried using reduceByKey, without success.
I also tried this: rdd.persist(MEMORY_AND_DISK).flatMap(...).reduceByKey .
However, I got the same error as before, namely the error described here:
Are you sure it's memory related? What is the disk utilization and IO
performance on the workers? The error you posted looks to be related to
shuffle trying to obtain block data from another worker node and failing to
do so in reasonable amount of time. It may still be memory related, but I'm

In the console, you'd find this draws a progress bar illustrating the
current stage progress. In logs, it shows up as this sort of 'pyramid'

You can turn it off with spark.ui.showConsoleProgress = false

If you do not want those progress indication to appear, just set

There is no direct way of doing that. If you need a Single file for every
batch duration, then you can repartition the data to 1 before saving.
Another way would be to use hadoop's copy merge command/api(available from
2.0 versions)

Actually saving to S3 is done in two steps:

2) commiting them to proper directory
Step 2) could be slow because S3 do not have a quick atomic move
