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.
