```
cd /usr/hdp/current/spark2-client
su spark
```

The following example uses _log4j.properties_ as the input file:

#### **4.2.1 Upload the input file to HDFS:**

```
hadoop fs -copyFromLocal /etc/hadoop/conf/log4j.properties
          s3a://testbucket/testdata
```

#### **4.2.2  Run the Spark shell:**

```
