HADOOP_HOME=<hadoop home>
XMX_SIZE="80g"
```
+
+ For the following cases, you don't need to specify `HADOOP_HOME` that will simplify the server deployment.
+ 1. using the storage type without HDFS like `MEMORY_LOCALFILE
+ 2. using HDFS and package with hadoop jars, like this: `./build_distribution.sh --hadoop-profile 'hadoop3.2' -Phadoop-dependencies-included`. But you need to explicitly set the `spark.rss.client.remote.storage.useLocalConfAsDefault=true`
+
3. update RSS_HOME/conf/server.conf, eg,
```
rss.rpc.server.port 19999
