---------------------------------
Summary: Balancer: make balancer to be a long service process for
easy to monitor it.
Key: HDFS-13783
URL: https://issues.apache.org/jira/browse/HDFS-13783
Project: Hadoop HDFS
Issue Type: New Feature
Components: balancer & mover
Affects Versions: 3.0.3
Reporter: maobaolong
If we have a long service process of balancer, like namenode, datanode, we can
get metrics of balancer, the metrics can tell us the status of balancer, the
amount of block it has moved,
We can get or set the balance plan by the balancer webUI. So many things we can
do if we have a long balancer service process.
So, shall we start to plan the new Balancer? Hope this feature can enter the
next release of hadoop.
