Hi, I am running bigger ALS on spark 1.2.0 on yarn (cdh 5.3.0) - ALS is using about 3 billions of ratings and I am doing several trainImplicit() runs in loop within one spark session. I have four node cluster with 3TB disk space on each. before starting the job there is less then 8% of the disk space used. while the ALS is running I can see the disk usage rapidly growing mainly because of files being stored under yarn/local/usercache/user/appcache/application_XXX_YYY/spark-local-ZZZ-AAA. after about 10 hours the disk usage hits 90% and yarn kills the particular containers. am I missing doing some cleanup somewhere while looping over the several trainImplicit() calls? taking 4*3TB of disk space seems immense. thanks for any help,Antony.
