6. Validating your Installation

Once you have installed HDP services, you should verify that they are working as expected. You can do this by running provided smoke tests.

Create a smoke test user directory in HDFS, if one does not already exist. From the Hadoop command line created during installation:
```
%HADOOP_HOME% \bin\hdfs dfs –mkdir –p /user/smoketest
        %HADOOP_HOME% \bin\hdfs dfs –chown –R smoketest
```
Establish that you want to run your smoketests as a hadoop user:
```
runas /user:hadoop
```

Run your smoketests:

“cmd /K %HADOOP_NODE%\Run-SmokeTests.cmd”
