             Summary: Metrics scm_pipeline_metrics_num_pipeline_creation_failed keeps increasin
                 Key: HDDS-1353
                 URL: https://issues.apache.org/jira/browse/HDDS-1353
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
          Components: SCM
            Reporter: Nanda kumar


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.
