Hey,
It's great to initiate MapR to slider!
Unfortunately, following the suggestions did not work (remove the classpath
modification on slider-env.sh and copied mapr's jars to slider's lib
folder).
I'm guessing support for parsing the fs.defaultFS string ("maprfs:///") has
to be added to Slider's code. Something similar to
https://issues.apache.org/jira/browse/FLINK-1006.
Should I just open an incident on Jira?
Thanks!
Nicolas
