Zhe Zhang updated HDFS-12421: ----------------------------- Component/s: metrics > 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, metrics > 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-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
