+### Configuring Drill to use AWS IAM Roles for Accessing S3
+
+If you use IAM roles/Instance profiles, to access data in s3, use the
following settings in your core-site.xml. Do not specify the secret key or
access key properties. As an example:
+
+ <configuration>
+ <property>
+ <name>fs.s3a.aws.credentials.provider</name>
+
<value>com.amazonaws.auth.InstanceProfileCredentialsProvider</value>
+ </property>
+ </configuration>
**Note:** When you rename the file, Hadoop support breaks if `$HADOOP_HOME`
was in the path because Drill pulls in the Drill core-site.xml file instead of
the Hadoop core-site.xml file. In this situation, make the changes in the
Hadoop core-site.xml file. Do not create a core-site.xml file for Drill.
