Flow parameter based condition is not working

[NidhiManek]

We want to define the flow of a dag based on the flow parameter passed to the dag. based on the value given to the flow parameter, we want to take call on whether to run a particular node or not. I have tried different ways but it's not working.

1. Generally, we access flow parameter in .flow file as {parameter_name}, when using {parameter_name} in the condition, azkaban gives error when uploading the zip.
   example:

condition: ${iwit_phase_name} == "P2-P1"

Validator Directory Flow reports errors: Invalid condition for DSP Trigger: cannot resolve the condition. Please check the syntax for supported conditions.

2. If we use {job_name:parameter_name} then azkaban allows to upload the zip but it is always evaluated false.
   example:

condition: ${DSP-Trigger-Optimizer-Recommendation:iwit_phase_name} == "Alpha-Synergy" || ${DSP-Trigger-Optimizer-Recommendation:iwit_phase_name} == "Alpha-Dedicated"

The concern is if we can access flow parameter as {parameter_name} in whole flow then why not in condition config. Can we please change the way azkaban parses the condition- always requiring job_name in the condition- as we should be able to access flow parameters without job_name and only JOB_PROP_FILE variables should be requiring job_name.

Thanks!
