+## Testing Alluxio
+It's pretty simple to test alluxio. Go to http://alluxio-master:19999  to check the status of alluxio.  And you can mount HDFS file to alluxio from alluxio client like below:
+```
+	1. docker-compose exec alluxio-master bash
+	2. alluxio fs mount /alluxio-dir hdfs://namenode:9000/somedir
+	3. check files from http://alluxio-master:19999 or from alluxio client.
+	4. alluxio fs ls /alluxio-dir
+```
+Altnatively, you can test the intergation with flink.  Just  follow the step:
+```
+1. docker-compose exec jobmanager bash
+2. cd /opt/flink/bin
+3. flink run ../examples/batch/WordCount.jar \
+  --input alluxio://alluxio-master:19998/LICENSE \
+  --output alluxio://alluxio-master:19998/output

 ## Run jobs on the docker platform.
 
 For java developers, I provide some tests over the platform. You can fork it from [here](https://github.com/spancer/flink-iceberg-demo), the test project
 contains flink jobs with set of components, such as kafka, elasticsearch, iceberg, etc.. Source and sink examples are fully inclued.
