How to connect to spark (CDH-5.8 docker vms at remote)? Do I need to map port 7077 at container? -


currently, can access hdfs inside application, i'd - instead of running local spark - use cloudera's spark enabled in cloudera manager.

righ have hdfs defined @ core-site.xml, , run app (--master) yarn. don't need set machine address hdfs files. in way, spark job runs locally , not in "cluster." don't want now. when try set --master [namenode]:[port] not connect. wonder if i'm directing correct port, or if have map port @ docker container. or if i'm missing yarn setup.

additionally, i've been testing snappydata (inc) solution spark sql in-memory database. goal run snappy jvms locally, redirecting spark jobs vm cluster. whole idea here test performance against hadoop implementation. solution not final product (if snappy local, , spark "really" remote, believe won't efficient - in scenario, bring snappy jvms same cluster..)

thanks in advance!

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
