i have spark job takes file 8 records hdfs, simple aggregation , saves hadoop. notice there hundreds of tasks when this. i not sure why there multiple jobs this? thought job more when action happened. can speculate why - understanding inside of code should 1 job , should broken down stages, not multiple jobs. why doesn't break down stages, how come breaks jobs? as far 200 plus tasks, since amount of data , amount of nodes miniscule, doesn't make sense there 25 tasks each row of data when there 1 aggregations , couple of filters. why wouldn't have 1 task per partition per atomic operation? here relevant scala code - import org.apache.spark.sql._ import org.apache.spark.sql.types._ import org.apache.spark.sparkcontext._ import org.apache.spark.sparkconf object testproj {object testproj { def main(args: array[string]) { /* set application name in sparkconf object */ val appconf = new sparkconf().setappname("test proj") /* env settings

this question has answer here: how % work in python? 17 answers for x in xrange(12): if x % 2 == 1: continue print x i know does, language doesn't make sense me. in particular second line lost. if x % 2 == 1 means "if x modulo 2 equals 1". modulo (or mod) remainder after division. so, example: 3 mod 2 = 1 12 mod 5 = 2 15 mod 6 = 3 for x mod 2, you're there's remainder if , iff x odd. (because numbers divisible 2 0 remainder.) likewise, odd numbers have remainder of 1. so x % 2 == 1 returns true if x odd.

this question has answer here: javascript code trick :what's value of foo.x 4 answers the assignment operator has right-to-left associativity. var x,y; x=y=1; works expected , x equals 1. consider code: var foo={}; foo.x = foo = {n: 2}; i expect above work following: var foo = {n: 2}; foo.x=foo; however, in first case foo.x undefined while in second case foo.x points foo (circular reference). explanation? javascript evaluates expressions left right. can show what's going on using additional variable: var foo = {}; var bar = foo; // keep reference object stored in foo foo.x = foo = {n: 2}; because of associativity, last statement parsed as: foo.x = (foo = {n: 2}); but because of evaluation order, foo.x runs first (determining store value), foo , {n: 2} . store {n: 2} in variable foo , assign same value property x of old con
