1)how pre-determine number of rdd partitions created? 2)what factors partitioning of data depend on? size of data , way stored(compressed, sequence etc..) for simplicity, assume have 6gb file in hdfs stored plain text file. my cluster ec2 cluster below config, 1 master node - m3.xlarge(4 cores, 15gb ram) 4 core nodes - m3.xlarge(4 cores , 15gb ram each) update: happens if same stored in s3, hbase or nosql? the partitions dependent on file type. in case, since hdfs file, default number of partitions number of input splits , depend on hadoop setup. if want way of understanding how works. from hadooprdd.getpartitions : val inputsplits = inputformat.getsplits(jobconf, minpartitions) val array = new array[partition](inputsplits.size)

i have question suppose there 2 tables customer cid name customerimage imgid cid here cid foreign key i know if want see images of customer write select customer.cid, customer.name , customerimage.imgid customer innerjoin customerimage customer.cid= customerimage.cid this shows list every image customer id , name what should add in if want show images of 1 cid in 1 column cid image name so image column should contain imgid customer i think want group images in 1 row each customer, can group_by clause , group_concat function in mysql: select c.cid , с.name , group_concat(ci.imgid separator ',') customer c join customerimage ci on c.cid = ci.cid group c.cid , c.name

okay, bear me on this, know it's going horribly convoluted, please me understand what's happening. from functools import partial class cage(object): def __init__(self, animal): self.animal = animal def gotimes(do_the_petting): do_the_petting() def get_petters(): animal in ['cow', 'dog', 'cat']: cage = cage(animal) def pet_function(): print "mary pets " + cage.animal + "." yield (animal, partial(gotimes, pet_function)) funs = list(get_petters()) name, f in funs: print name + ":", f() gives: cow: mary pets cat. dog: mary pets cat. cat: mary pets cat. so basically, why not getting 3 different animals? isn't cage 'packaged' local scope of nested function? if not, how call nested function local variables? i know running these kind of problems means 1 'doing wrong', i'd understand happens. the nested function loo...

how access child method eg.? class { public function start() { // somehow call run method on b class inheriting class } } class b extends { public function run() { ... } } $b = new b(); $b->start(); // should call run method class a should not try call methods not define. work fine scenario: class { public function start() { $this->run(); } } however, fail terribly should this: $a = new a; $a->start(); what you're trying here sounds use case abstract classes: abstract class { public function start() { $this->run(); } abstract function run(); } class b extends { public function run() { ... } } the abstract declaration precisely prevent shooting own foot trying instantiate , start a without extending , defining required methods.

i have list of dataframes , need transform variable in each of dataframes factor. e.g. mylist <- list(df1 = data.frame(a = sample(10), b = rep(1:2, 10)), df2 = data.frame(a = sample(10), b = rep(1:2, 10)) ) lets variable b needs factor in each dataframe. i've tried this: tmp <- setnames(lapply(seq_along(mylist), function(x) apply(mylist[[x]][c("b")], 2, factor)), names(mylist)) but returns transformed variable, not whole dataframe need. know how loop, don't want resort that. per comment david arenburg, solution should work: tmp <- lapply(mylist, function(x) {x[, "b"] <- factor(x[, "b"]) ; x}) ; str(tmp)
