Hadoop streaming with python on Windows -

-

i'm using hortonworks hdp windows , have configured master , 2 slaves.

i'm using following command;

bin\hadoop jar contrib\streaming\hadoop-streaming-1.1.0-snapshot.jar -files file:///d:/dev/python/mapper.py,file:///d:/dev/python/reducer.py -mapper "python mapper.py" -reducer "python reduce.py" -input /flume/0424/userlog.mdac-hd1.mdac.local..20130424.1366789040945 -output /flume/o%1 -cmdenv pythonpath=c:\python27

the mapper runs through fine, log reports reduce.py file wasn't found. in exception looks hadoop taskrunner creating symlink reducer mapper.py file.

when check job configuration file, noticed mapred.cache.files set to;

hdfs://mdac-hd1:8020/mapred/staging/administrator/.staging/job_201304251054_0021/files/mapper.py#mapper.py

it looks although reduce.py file being added jar file, it's not being included in configuration correctly , can't found when reducer tries run.

i think command correct, i've tried using -file parameters instead neither file found.

can see or know of obvious reason?

please note, on windows.

edit- i've run locally , worked, looks problem may copying of files round cluster.

still welcome input!

well, thats embarrassing... first question , answer myself.

i found problem renaming hadoop conf file force default settings meant local job tracker.

the job ran , gave me room work out problem is, looks communication around cluster isn't complete need be.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
