[Swift-devel] SGE's qstat output parsing failure

[Luiz Gadelha]

Hi,

There is a small bug in the parsing of SGE's qstat output lines. For the following qstat output:

job-ID  prior   name       user         state submit/start at     queue                          slots ja-task-ID

 543310 0.50500 null       lgadelha     r     11/22/2011 14:40:38 linux.q at cmm11bl5.hpc.lncc.br       1        
 ...

QueuePoller incorrectly assumes that the job identifier is in the same position as "job-ID" in the header, which is not the case above, where it finds a space character and returns an empty string as the job identifier, Swift fails with a "Failed to parse qstat line" message. The attached log file is from a simple test script run that presents this problem.

The attached patch fixed the problem in my environment.

Regards,

Luiz
