Daniel Dai commented on PIG-2165:
---------------------------------
Hi, Julien,
PIG-2165-1.patch does use global variable PigContext.params to pass params.
What it does is:
1. Put params into PigContext.params when processing command line
2. Adding PigContext.params to do variable binding:
{code}
// plist is the variable array to bind
if (getScriptContext().getPigContext().getParams()!=null) {
for (String param : getScriptContext().getPigContext().getParams())
{
plist.add(param);
}
}
// Use plist to do the binding
{code}
3. For param_file, instead of reading and put into params, I delegate it to
ParameterSubstitutionPreprocessor, which already handles parameter_file:
{code}
psp.genSubstitutedFile(in, writer, plist.toArray(params),
scriptContext.getPigContext().getParamFiles().toArray(type1));
{code}
4. I also did some refactory in main() to use PigContext.params
> Need a way to deal with params and param_file in embedded pig in python

> I am using embedded pig in python and cannot pass param key value pairs to
> the python script. The only way to pass params seem to be by passing it in
> the bind command.
> Is there a plan to have command line parameters to a pig embedded python
> script? Similar needs for param_file and using the environment variables.
> Thanks
