-----------------------------------
This issues is seen in blockade test
({{blockade/test_blockade_client_failure.py::test_client_failure_isolate_two_datanodes}})
Steps to reproduce:
1. Build Ozone: {{mvn clean install package -Phdds -Psrc -Pdocker -Pdist -Dtar
-DskipTests}}
2. {{cd hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/tests}}
3. python2 -m pytest -s
blockade/test_blockade_client_failure.py::test_client_failure_isolate_two_datanodes
Note: The test-case doesn't fail always, try it couple of times.
