What happened?
I tried to use the opentelemetry.sdk.trace.ConcurrentMultiSpanProcessor for a library but get an error on shutdown.
Steps to Reproduce
Based on the basic_trace.py example:
from opentelemetry import trace
from opentelemetry.sdk.trace import (
ConcurrentMultiSpanProcessor,
TracerProvider,
)
from opentelemetry.sdk.trace.export import (
BatchSpanProcessor,
ConsoleSpanExporter,
)
span_proc = ConcurrentMultiSpanProcessor()
span_proc.add_span_processor(BatchSpanProcessor(ConsoleSpanExporter()))
trace.set_tracer_provider(TracerProvider())
trace.get_tracer_provider().add_span_processor(span_proc)
tracer = trace.get_tracer(__name__)
with tracer.start_as_current_span("foo"):
print("Hello world!")Running with:
python basic_trace.py
Expected Result
Hello world!

},

}
}

RuntimeError: cannot schedule new futures after shutdown
Additional context
I can avoid the error by manually shutting down in the end of the script:
trace.get_tracer_provider().shutdown()But since the tracer provider already calls shutdown on exit, can't this be handled automatically without the manual shutdown?
Would you like to implement a fix?
