> When loading a coprocessor from hdfs, the jar file gets copied to a path on the local
filesystem, which depends on the region name, and the region start key. The name is "cleaned",
but not enough, so when you have filesystem unfriendly characters (/?:, etc), the coprocessor
is not loaded, and an error is thrown
