URL: https://github.com/apache/hadoop/pull/8335#issuecomment-4901003125
Rebased this branch onto current `apache/trunk` so the GitHub Build
detection check can see a current base, and kept the reviewer-requested
`tolerancePercent > 0` guard in place.\n\nLocal validation on the rebased head:
`JAVA_HOME=/opt/homebrew/opt/openjdk@17/libexec/openjdk.jdk/Contents/Home
./mvnw -Dmaven.repo.local=/tmp/hadoop-m2 -pl hadoop-hdfs-project/hadoop-hdfs
-am -Dtest=TestNodePlan -DskipTests=false test`
> DiskBalancer: Plan command support with tolerancePercentage.

> The tolerance percent specifies when we have reached a good enough value for
> any copy step. For example, if you specify 10% then getting close to 10% of
> the target value is good enough.{code}
> Currently, only *{{maxDiskErrors}}* and *{{bandwidth}}* are passed in the
> plan, and it is expected that *{{tolerancePercentage}}* can also be
> propagated to the DataNode.
