tFileList does not clean his global variables

Lorenzo5 — Thu, 13 Dec 2018 14:04:52 GMT

Scenario: a loop on dates (for example) and within any iteration a tFileList component look for specific files.

Well, when the component does not find any file, the global variables (in particular tFileList_2_CURRENT_FILEPATH) are not cleaned.

the bold line you see below is a:

System.out.println(globalMap.get("tFileList_2_CURRENT_FILEPATH"));

performed by a tJava component which follows the tFileList component itself.

I can check also for ((Integer)globalMap.get("tFileList_2_NB_FILE")) of course, but I was expecting to have the global variable set by the component cleaned before any of its execution.

Hi,

Could you please share a screen shot of your job and component detail screenshot so that we will get a better idea about the use case?

@lorenzolucioni

Thanks for the diagram and I got a better idea of your problem.

You are using OnSubJobOk and OnComponentOk after getting the data from filter and we may not get the desired way of data flow here.

Instead, can we break the flow to two simple flows here? Following are the steps to do it.

a) After tfilterrow, push the output data to a tHashOutput

b) To execute the plain logs, use the below components.

tHashInput (from previous stage output) -> tFlowtoIterate -> tFlisList ---- (if)----- > tRunJob Child

c) Again read the same hash to execute the gZipped logs

tHashInput (from previous stage output) -> tFlowtoIterate -> tFlisList ---- (if)----- > tRunJob Child

This time, mark the option to clear the hash after reading .

I believe, it should resolve your issue. If it has helped in issue resolution, could you please mark the topic as resolved? Kudos are also welcome 🙂

Warm Regards,
