I replied to the SO question with more details. The issue is that your trying to load a truststore (file) on the VM which doesn't exist. You need to make that file accessible in some way. The other SO question ( https://stackoverflow.com/questions/42726011/truststore-and-google-cloud-dataflow?noredirect=1&lq=1) has a code snippet where the user copies the truststore from GCS to a local tmp file path and the configures the map with that temp file path.
