------------------------------------
Summary: [DiskBalancer] Show EstimatedBytesToMove only during
active balancing and improve threshold check message
Key: HDDS-14110
URL: https://issues.apache.org/jira/browse/HDDS-14110
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Gargi Jaiswal
Assignee: Gargi Jaiswal
This ticket resolves the bugs found out :
* {{EstimatedBytesToMoved}} and {{EstimatedTimeLeft}} should not be shown up
if no container movement happens.
* Improve threshold validation error message. When running the DiskBalancer
update command with a threshold value of {*}100.0{*}, the operation fails on
all datanodes with the following error:
{code:java}
bash> ozone admin datanode diskbalancer update -t 100.0 --in-service-datanodes
Error on node [DN-1]: Threshold must be a percentage(double) in the range 0 to
100.{code}
*Suggested improvement:*
A Threshold value can never be 100.0% as it would mean allow moving 100% of a
disk's contents, effectively emptying one disk. Rather the error message should
clarify that 100 is excluded.
new error msg:
{code:java}
Error on node [DN-1]: Threshold must be a percentage(double) in the range 0 to
100. (0 inclusive, 100 exclusive){code}
