Subject debug script not found
Date Fri, 14 Oct 2011 07:26:55 GMT
hi,guys
 I'm debuging pipes program on mapreduce, and trying debug script to print
some debug info.

 I used the default pipes script under src/c++/pips/debug, and put it on
hdfs, create a symlink in distcache

 But it does not work while printing "exec: pipes-default-script : no
found".
 Does that message printed mean  pipes-default-script is not under the
task's work dir?
 I print the work dir as following:

attempt_201110141512_0001_m_000000_1
        │   ├── job.xml
        │   ├── split.info
        │   └── work
        │       ├── jobTokenPassword
        │       ├── pipes-default-script ->
/home/test/hadoop/mapred_tmp/taskTracker/distcache/4497768195926406270_-287867232_17995480/localhost/resource/pipes-default-script
.....
pipes-default-script is under the work dir.

SO what's the solution ?
