I launched a job on a sample set that aggregates a file on each sample to one big file on the sample set. The sample set has about 10,000 samples, and this resulted in the docker run command line being about 3MB long. The JES log shows this error after the docker run command:
2017/08/09 20:30:27 E: command start failed: (fork/exec /usr/bin/docker: argument list too long)
It looks like every input file is named individually on the docker run command line.
The failing submission is 2934ffda-4655-4633-bca6-cf9bfc9b6c19
