deepujain commented on PR #8335:
URL: https://github.com/apache/hadoop/pull/8335#issuecomment-5183072067
No code changes here since the August 4, 2026 rebase onto current
`apache/trunk`.
On the refreshed head, Apache Yetus is green,
`continuous-integration/jenkins/pr-merge` is green, and this PR is still
approved. The remaining GitHub Build failure is in the fork-side `rockylinux_8`
image/container path rather than the DiskBalancer test lanes themselves.
If there is nothing else you would like changed here, this looks ready for
merge once that external Build signal is no longer a blocker.

> {code:java}
> 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.
