Could it be that the path entries in spark.ini and starter.ini are different from the filenames?
There are some plugins or libs named filename.jar.pack in the spark installation directory. But after starting Spark for the first time these files are renamed to only filename.jar. But the path entries in spar.ini and starter.ini remain filename.jar.pack.
For me this seems to be the reason for some logged errors we get.
Is that a correct behaviour or a so called bug?
Is there a manual to get to now which intentions these files have?
