hadoop - Which version of Spark to download? -


i understand can download spark source code (1.5.1), or prebuilt binaries various versions of hadoop. of oct 2015, spark webpage http://spark.apache.org/downloads.html has prebuilt binaries against hadoop 2.6+, 2.4+, 2.3, , 1.x.

i'm not sure version download.

i want run spark cluster in standalone mode using aws machines.

<edit>

i running 24/7 streaming process. data coming kafka stream. thought using spark-ec2, since have persistent ec2 machines, thought might use them.

my understanding since persistent workers need perform checkpoint(), needs have access kind of shared file system master node. s3 seems logical choice.
</edit>

this means need access s3, not hdfs. not have hadoop installed.

i got pre-built spark hadoop 2.6. can run in local mode, such wordcount example. however, whenever start up, message

warn nativecodeloader: unable load native-hadoop library platform... using builtin-java classes applicable

is problem? need hadoop?

<edit>

it's not show stopper want make sure understand reason of warning message. under assumption spark doesn't need hadoop, why showing up? </edit>

we're running spark on ec2 against s3 (via s3n file system). had issue pre-built versions hadoop 2.x. regrettably don't remember issue was. in end we're running pre-built spark hadoop 1.x , works great.

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
