Subject RDD pipe example. Is this a bug or a feature?
Date Fri, 19 Sep 2014 18:21:20 GMT
Hi

I am wrote a little java job to try and figure out how RDD pipe works.
Bellow is my test shell script. If in the script I turn on debugging I get
output. In my console. If debugging is turned off in the shell script, I do
not see anything in my console. Is this a bug or feature?

I am running the job locally on a Mac

Thanks

Andy


Here is my Java

        rdd.pipe(pwd + "/src/main/bin/RDDPipe.sh").collect();



#!/bin/sh 



#

# Use this shell script to figure out how spark RDD pipe() works

#



set -x # turns shell debugging on

#set +x # turns shell debugging off



while read x ; 

do 

echo RDDPipe.sh $x ;

Done



Here is the output if debugging is turned on

$ !grep

grep RDDPipe run.sh.out

+ echo RDDPipe.sh 0

+ echo RDDPipe.sh 0

+ echo RDDPipe.sh 2

+ echo RDDPipe.sh 0

+ echo RDDPipe.sh 3

+ echo RDDPipe.sh 0

+ echo RDDPipe.sh 0

$
