Erik Krogen created HDFS-12421: ---------------------------------- Summary: Balancer to emit standard metrics Key: HDFS-12421 URL: https://issues.apache.org/jira/browse/HDFS-12421 Project: Hadoop HDFS Issue Type: Improvement Components: balancer & mover Reporter: Erik Krogen Assignee: Erik Krogen Priority: Minor
The Balancer currently prints some statistics about its operation to stdout while it is running. This is fine if the balancer is manually run via CLI by an operator, but for the more common case of it being a scheduled execution, it is cumbersome to have to track down the logs to be able to monitor its progress. We already have a standard metrics system in place; I propose that we have the Balancer emit metrics while it is running so that they can be tracked via standard metrics infrastructure. We can start with just the things that the balancer already prints to stdout: bytes already moved, bytes left to move, bytes currently being moved, and iteration number. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
