On a brand new instance of Brisk on an Ubuntu server, when I try to run a job I get the following error:
Exception in thread "main" java.io.IOException: No FileSystem for scheme: cfs
at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:1307)
at org.apache.hadoop.fs.FileSystem.access$100(FileSystem.java:65)
...
I read on the forums that this can be caused by Brisk's core-site.xml not being in the classpath, but I checked and it is in the classpath. Here's the classpath being used to launch Brisk via jsvc:
