Hope you all are doing well. I am Vinay, recently started working on HTC Condor as a part of my project. I want to skip few nodes depending on the input file provided, as of now i have written a pre script which checks my input and sends a exit status and this exit status is captured and used to skip or run a node in PRE_SKIP step.
The scenario is this,For a particular pipeline, I have three possible inputs. Either 'A' file, 'B' file or Both 'A' and 'B' file.
So, When 'B' file is the input, exit status given by pre script is 1when 'A' files is the input, exit status given by pre script is 2when both B' and 'A' files are used as input, exit status is 0.The pre script name is check_input.py
My PRE SCRIPT and PRE_SKIP statements in .dag file are :-
SCRIPT PRE CREATE_B logs/check_input.pySCRIPT PRE TARGET_B logs/check_input.pyPRE_SKIP CREATE_B 2PRE_SKIP TARGET_B 2SCRIPT PRE PICK_A logs/check_input.pySCRIPT PRE STAT_A logs/check_input.pyPRE_SKIP PICK_A 1PRE_SKIP STAT_A 1
So, When i am running 'B' file as input, the exit status is 1. The nodes belonging to 'A' files in the above code as skipped as expected by exit status of 1 but when the execution reaches CREATE_B node, this node is exited by same exit status of 1.
So, After analysing the situation, I believe there can be two issues :-1) Is it allowed to use multiple PRE_SKIP statements with different exit code as it did above?2) Does the order of ABORT-DAG-ON of nodes have any impact on the premature exit of above node?
Looking forward to your reply.Thank you.
