i looking guide regarding how install spark on existing virtual yarn cluster. i have yarn cluster consisting of 2 nodes, ran map-reduce job worked perfect. looked results in log , working fine. now need add spark installation commands , configurations files in vagrantfile. can't find guide, give me link ? i used guide yarn cluster http://www.alexjf.net/blog/distributed-systems/hadoop-yarn-installation-definitive-guide/#single-node-installation thanks in advance! i don't know vagrant, have installed spark on top of hadoop 2.6 (in guide referred post-yarn) , hope helps. installing spark on existing hadoop easy, need install only on one machine. have download 1 pre-built hadoop version it's official website (i guess can use without hadoop version need point direction of hadoop binaries in system). decompress it: tar -xvf spark-2.0.0-bin-hadoop2.x.tgz -c /opt now need set environment variables. first in ~/.bashrc (or ~/.zshrc ) can set spark

i have application implements deviceadminreceiver . when user attempts unlock device, able determine method (e.g., pin or fingerprint reader) used. the reason because possible fingerprint reader errors exceed threshold failed unlocks specified user's policy, , when happens, user's data wiped device manager. poor user experience lose data because hand brushed against phone in bag while looking else. able smarter how fingerprint scanner failures counted against policy threshold vs. how pins or password attempts counted. as far can tell, android not give me information, thought might ask wider community on chance i'm missing something.

i trying analyze around 50-60 gb of data. thought of using spark that, not have access multiple nodes in cluster. can level of processing done using spark standalone mode ? if yes, know estimated time required process data.thanks! short answer: yes. spark partition file in many smaller chunks. in case few chunks executed @ time. these few chunks should fit in memory (you need play configurations right) to summarize, able it, faster if had more memory/cores can processes more things in parallel.

i have exercise error , love on error , how fix exercise. write recursive function receives set of numbers , number between 9-1. function returns true if there continuity of numbers 1 number, otherwise returns false. it brings me true, there no error. examples: for array 3,1,2,3,4,6,3 , number 4 returned true for array 3,1,2,1,2,3,5 , number 4 returned false the code: public static boolean continuityofnumbers(int[] arr, int n) { int counter = 0; int index = arr.length - 1; if (n == 0) return true; if (arr[index] - 1 == arr[index - 1]) counter += 1; index--; return continuityofnumbers(arr, n - 1); } here o(n) runtime , storage complexity solution. makes boolean continuity array , checks , end of recursion. don't copy-paste it, make sure read comments in code see logic is, , make sure understand it. it additionally pre-validation checks make sure n contained , reachable in array
