Yiqun Lin reassigned HDFS-10600:
--------------------------------
Assignee: Yiqun Lin
> PlanCommand#getThrsholdPercentage should not use throughput value.
> ------------------------------------------------------------------
>
> Key: HDFS-10600
> URL: https://issues.apache.org/jira/browse/HDFS-10600
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: diskbalancer
> Affects Versions: 2.9.0, 3.0.0-beta1
> Reporter: Lei (Eddy) Xu
> Assignee: Yiqun Lin
> Fix For: 2.9.0
>
>
> In {{PlanCommand#getThresholdPercentage}}
> {code}
> private double getThresholdPercentage(CommandLine cmd) {
> ....
> if ((value <= 0.0) || (value > 100.0)) {
> value = getConf().getDouble(
> DFSConfigKeys.DFS_DISK_BALANCER_MAX_DISK_THRUPUT,
> DFSConfigKeys.DFS_DISK_BALANCER_MAX_DISK_THRUPUT_DEFAULT);
> }
> return value;
> }
> {code}
> {{DISK_THROUGHPUT}} has the unit of "MB", so it does not make sense to return
> {{throughput}} as a percentage value.
> Btw, we should use {{THROUGHPUT}} instead of {{THRUPUT}}.
