This patch was tested with unit tests, robot tests and manual tests. One can manually test the patch by compiling locally and bringing up a cluster via docker by ``` cd hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/compose/ozone docker-compose up -d ``` Then pointing the browser to localhost:9888 This will bring up datanodes UI in Recon as the default. Scale up the number of datanodes or create keys in ozone via freon and see the change in Recon UI. ``` docker-compose scale datanode=6 ozone freon rk --replicationType=RATIS --numOfVolumes=10 --numOfBuckets=10 --numOfKeys=10 --factor=THREE --numOfThreads=20 ```
