---------------------------------------
Summary: Distributed unique IDs are not unique
Key: SYSTEMML-1127
URL: https://issues.apache.org/jira/browse/SYSTEMML-1127
Project: SystemML
Issue Type: Bug
Components: ParFor
Reporter: Felix Schüler
When executing a Spark parfor, the SparkParforWorker throws an exception which
states that the localtmpdir could not be created. This is due to the fact that
multiple executors are running multithreaded on the same worker.
The createDistributedUniqueID() method in the IDHander.java creates unique IDs
only per pid and host, not per thread. This could potentially be solved by
adding the threadID to the unique ID.
