java - launch and submit job spark -


i try "run" spark jobs width java application, searching, found following 2 methods: clientsarguments , sparklauncher.

could explain me difference between two? difference between launch , submit job/application spark? thank you.

sparklauncher wrapper library spark-submit, coverts sparklauncher code spark-submit script , trigger jobs.

the mechanism same spark-submit script, if @ source code of sparklauncher, uses processbuilder construct shell.

if want use sparklauncher, need specify $java_home, $sprak_home , other essential parameters. there limitation sparklauncher, machine sparklauncher runs must have $java_home , $spark_home(spark library) used sparklauncher locating script , related dependencies. soft of impossible cloud environment cloudfoundry etc.

you assume sparklauncher equals spark-submit script, choose client or master, local or yarn mode.

clientsarguments class yarn script, works yarn-mode.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
