---------------------------------
Summary: Fix TestDFSAdmin.testAllDatanodesReconfig flaky test
Key: HDFS-17885
URL: https://issues.apache.org/jira/browse/HDFS-17885
Project: Hadoop HDFS
Issue Type: Bug
Components: dfsadmin
Affects Versions: 3.5.0, 3.5.1
Reporter: Shilun Fan
Assignee: Shilun Fan
{*}Problem{*}{*}{*}
`TestDFSAdmin.testAllDatanodesReconfig` fails because it invokes
reconfiguration twice on the same DataNodes, causing the second invocation to
fail with "Another reconfiguration task is running."
*Solution*
- Start reconfiguration only once by calling `admin.startReconfigurationUtil()`
directly
- Capture output to ByteArrayOutputStream for assertions
- Improve test robustness: use `NUM_DATANODES` constant, stream-based counting
instead of fixed positions
- Remove unnecessary `Thread.sleep(1000)`
