-------------------------------------------
Summary: [DiskBalancer] Unexpected diskBalancer directory
appearing outside hdds directory in Ozone Datanode Layout
Key: HDDS-14114
URL: https://issues.apache.org/jira/browse/HDDS-14114
Project: Apache Ozone
Issue Type: Bug
Reporter: Elavarasan Kathirvel
Assignee: Gargi Jaiswal
While inspecting the Ozone datanode directory layout, an unexpected
{{diskBalancer}} directory was found outside the expected {{hdds}} directory
hierarchy.
*Expected behavior:*
The {{diskBalancer}} directory should appear {*}only under{*}{{}}
{code:java}
.../hdds/<cluster-id>/current/tmp/diskBalancer{code}
*Observed result:*
A second {{diskBalancer}} directory is appearing under:
{{}}
{code:java}
.../hadoop-ozone/datanode/data/tmp/diskBalancer{code}
{{}}
*Directory tree:*
{code:java}
[root disk1]# tree -d
