cannot start the transform script. reason : "argument list too long"

Hi,

I have a hive script [given below] which calls a python script using
transform and for large datasets [ > 100M rows ], the reducer is not able to
start the python process and the error message is "argument list too long".
The detailed error stack is given below.

The python script takes only 1 static argument "hbase". For small datasets [
1M rows ], the script works fine.

   1. Is this problem related to the number of open file handles on the
   reducer box?
   2. How do I get the correct error message?
   3. Is there a way to get to the actual unix process with arguments it is
   instantiating?

Thanks,
Irfan

Re: cannot start the transform script. reason : "argument list too long"

Posted by Dave Brondsema <db...@geek.net>.
We've gotten this error a couple of times too - it is very misleading, not
correct at all.  IIRC, I determined the root cause is selecting too many
input files (even though those do NOT get passed as arguments to transform
script).  For example, this happened once we had a lot of dynamic partitions
and were querying from too many at once.  Hope that helps!

Re: cannot start the transform script. reason : "argument list too long"

Posted by Irfan Mohammed <ir...@gmail.com>.
Yes. That is the command it is executing but what I do not understand is why
I am getting "argument list too long" when I am running the same sql with
the same python script with a large dataset.

Thanks.

RE: cannot start the transform script. reason : "argument list too long"

Posted by Steven Wong <sw...@netflix.com>.
Looks like this is the command line it was executing:

2011-03-01 14:46:13,733 INFO org.apache.hadoop.hive.ql.exec.ScriptOperator: Executing [/usr/bin/python2.6, user_id_output.py, hbase]

Thanks Ajo.

The hive sql and the python script run fine with a dataset of ( < 10M ) records. It is only when running with a large dataset of ( > 100M ) records, that I run into this error. I have been trying to get to the number of records (10-100M) or the invalid data which is causing the error.

I am trying to get to the actual error from the UnixProcess instantiation.

try something like this:

... and a #! line with the location of the python binary.

I think you can include a parameter too in the call like :
using 'user_id_output.py hbase'

Cheers,

Hi,

I have a hive script [given below] which calls a python script using transform and for large datasets [ > 100M rows ], the reducer is not able to start the python process and the error message is "argument list too long". The detailed error stack is given below.

The python script takes only 1 static argument "hbase". For small datasets [ 1M rows ], the script works fine.

 1.  Is this problem related to the number of open file handles on the reducer box?
 2.  How do I get the correct error message?
 3.  Is there a way to get to the actual unix process with arguments it is instantiating?
Thanks,
Irfan

Re: cannot start the transform script. reason : "argument list too long"

Posted by Irfan Mohammed <ir...@gmail.com>.
Thanks Ajo.

The hive sql and the python script run fine with a dataset of ( < 10M )
records. It is only when running with a large dataset of ( > 100M ) records,
that I run into this error. I have been trying to get to the number of
records (10-100M) or the invalid data which is causing the error.

I am trying to get to the actual error from the UnixProcess instantiation.

Re: cannot start the transform script. reason : "argument list too long"

Posted by Ajo Fod <aj...@gmail.com>.
instead of

using 'python2.6 user_id_output.py hbase'

try something like this:

using 'user_id_output.py'
... and a #! line with the location of the python binary.

I think you can include a parameter too in the call like :
using 'user_id_output.py hbase'

Cheers,
Ajo.
