GraphChi writes a lot of temporary files (edata,intervals...). After running the sharding, ALS encounters an error while reading a .apj belonging to shard 152 (which does not exist, 151 being the latest).
I wonder if I did something wrong with userids and itemids? More details in the attachment (with command I ran).
