File Tail and Pipeline Finisher precondition error

edit

Hi,

I'd like to read from a file and stop my pipeline when every rows has been loaded.

I got an Error in Pipeline Finisher becaouse the precondition is wrong for the File Tail event. Could you send me an example what shoud I write in the precondition of the Pipeline Finisher if I'd like to stop my pipeline when all records is loaded from the source file.

I read a static file and the the file is not modified while the pipeline is running.

I'd like to check the END event at the end of the loading process - From documentation: event Event that generated the record. Uses one of the following values: START - File Tail started processing the specified file. END - File Tail completed processing the contents of the file.

The error message/stack trace and the precondition is the following:

COMMON_0001 - Stage precondition: CONTAINER_0051 - Unsatisfied precondition(s) '${record:eventType()=='END'}'
com.streamsets.pipeline.api.base.OnRecordErrorException: COMMON_0001 - Stage precondition: CONTAINER_0051 - Unsatisfied precondition(s) '${record:eventType()=='END'}'
