Metrics scm_pipeline_metrics_num_pipeline_creation_failed keeps increasing
because of BackgroundPipelineCreator.
URL: https://github.com/apache/hadoop/pull/681
There is a BackgroundPipelineCreator thread in SCM which runs in a fixed
interval and tries to create pipelines. This BackgroundPipelineCreator uses
IOException as exit criteria (no more pipelines can be created). In each run of
BackgroundPipelineCreator we exit when we are not able to create any more
pipelines, i.e. when we get IOException while trying to create the pipeline.
This means that scm_pipeline_metrics_num_pipeline_creation_failed value will
get incremented in each run of BackgroundPipelineCreator.
