Hey there! Would you mind providing some more info about the job that's failing? Also, is there any additional output preceding the error in the error log? ---

Also would be helpful if you were to tell us which version being used and if on cloud, ECE, or standalone nodes. ---

Please see this for the possible solution: > [@Machine Learning: Could not create job](https://discuss.elastic.co/t/machine-learning-could-not-create-job/122037/4): > > Communications between the elasticsearch JVM and the autodetect process (which ML runs) is done via named pipes, these pipes are created in /tmp. In the log there is a message that you posted, it mentions that a file in ES\_HOME/tmp cannot be read. This /tmp directory must be readable, if it is mounted with no\_exec then autodetect cannot start. /tmp is the default temporary directory the JVM uses but you can change this with the JVM option: -Djava.io.tmpdir=/var/data/elasticsearch/tmp You cou… ---
