Amazon S3 - Report generation leads to multipart upload failed error

Issue

Cannot generate reports on Liferay 6.2 and Amazon S3
Hitting multipart upload error when creating CSV file

Scenario - With an S3 bucket configured for use and a data-definition in place, we find that when attempting to generate a report (.csv format), it is possible to encounter the following error:
```
multipart upload failed
```

Environment

Liferay Portal 6.2

Resolution

This is known behavior with the S3 API when uploading an empty file (0 bytes). See: https://github.com/aws/aws-sdk-php/issues/1649

1. This workaround involves a tweak to our configuration of Jasper Reports. It is better to have empty sections or no-data sections, over having an empty file generated.

For a report template, set attribute "When No Data Type" instead to "No Data Section" or "All Sections No Detail"

Screenshot uses Jaspersoft Studio 6.9.0

2. To your data-definition file add the corresponding component into the <jasperReport> tag:

whenNoDataType="AllSectionsNoDetail"

whenNoDataType="NoDataSection"

*Further attributes can be added to the <noData></noData> tags. For example:

<noData>
       <band height="10">
             <staticText>
             <reportElement x="" y="" width="" height="" uuid=""/>
             <box>
             <bottomPen lineWidth="" lineColor=""/>
             </box>
             <text><![CDATA[message here]]></text>
             </staticText>
       </band>
</noData>
