I have a feeling it is this 64 bit thing which is causing the broken pipes. Check on the cluster and the dev machine.
Just updated the question/problem description - but the C++ binary wasn't statically linked and so was looking for the . So's. After rectifying this, I am seeing these errors.
– decimus phostle Jul 27 at 15:13 can you check the job tracker logs, for each some of these failed attempts and see what it says in stderr section – bronzebeard Jul 27 at 15:44 I looked at the jobtracker logs, I don't see anything obvious. Also, would you happen to know how to get the JVM to print out the entire stacktrace? Currently it prints out a bunch and then truncates it with ... 7 more.
– decimus phostle Jul 27 at 16:38 Moreover, the stderr for all the attempts just seems to have the following: $more /usr/local/dp/hadoop/userlogs/job_201107211831_0013/attempt_201107211831_0013_m_?000000_0/stderr Hadoop Pipes Exception: Aborted by driver – decimus phostle Jul 27 at 16:39 you can view the logs for each attempt as well, what do those logs say. For eg. http://:50030/jobfailures. Jsp?
Jobid=job_201107211831_0013&kind=map&cause=k? Illed and then click on 4kb, 8kb or all – bronzebeard Jul 27 at 17:45.
So I gave it another shot and started from scratch. This time round I had better success. Here is the code and the config files I used.
Also, here's the command I used to run the job: hadoop pipes -conf path/to/dp_hpt_conf. Xml -input /path/to/input -output /path/to/output The input files in the /path/to/input were: $hadoop fs -ls /path/to/input Found 3 items -rw-r--r-- 3 dp dpgrp 25 2011-07-26 23:24 /path/to/input/bar -rw-r--r-- 3 dp dpgrp 87 2011-07-26 23:24 /path/to/input/baz -rw-r--r-- 3 dp dpgrp 44 2011-07-26 23:24 /path/to/input/foo $hadoop fs -get /path/to/input/foo . $cat foo The quick brown fox jumps over the lazy dog And the output was: $ hadoop fs -get /path/to/output/part-00000 .
$ cat part-00000 another 3 be 2 brown 2 dog 2 end 2 for 2 fox 2 input 2 is 3 jumps 2 lazy 2 of 2 over 2 program 2 quick 2 sentence 3 should 2 test 2 that 2 the 5 this 4 yet 2 (Apologies for the wonky paths. My actual paths were different - the paths here are just my lazy attempts at anonymizing them. ).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
