Are you sure that pyarrow is deployed on your slave hosts ? If not, you will either have to get it installed or ship it along when you call spark-submit by zipping it up and specifying the zipfile to be shipped using the --py-files zipfile.zip option
A quick check would be to ssh to a slave host, run pyspark and try to import pyarrow.
