Changes for ByteArrayToStringCoverter.
Malhar repository contains open source operator and codec library that can be used with the DataTorrent platform to build Realtime streaming applications. In addition to the library there are benchmark, contrib, demos, webdemos and samples folders available. Demos contain demo applications built using the library operators. Webdemos contain webpages for the demos. Benchmark contains performance testing applications. Contrib contains additional operators that interface with third party softwares. Samples contain some sample code that shows how to use the library operators.

The Malhar repository is on github.com. You can download or clone it using the GitHub links. If you already have a GitHub account you can fork the DataTorrent/Malhar repository and contribute with pull requests. See Contributing section below.
The project uses maven to build the code. To build the code run mvn install at the top level. The code also has a dependency to the DataTorrent API. The API releases are available in the DataTorrent maven repository and the Malhar pom.xml is configured with it. Individual modules such as library can be built independently by changing directory to the module and running maven there.
To run the code DataTorrent platform is needed. The developer version or an evaluation version, both of which are free, can be downloaded from
Please follow the instructions in the software README on how to run the application.
For an easer setup, sandbox virtual machine provides pre-configured DataTorrent platform with all necessary dependencies, and can be found in the download section.
Multiple demos are provided with the DataTorrent platform to showcase the platform and provide application development examples. Demos can be executed after downloading and installing DataTorrent platform or the sandbox with pre-configured DataTorrent platform environment. See demos source code for application development examples.
Web interface for the following demos is available:
Web apps run on Node.js. Please see webapps for more information.
When working with JIRA to submit pull requests, please use smart commits feature by specifying MLHR-XXXX in the commit messages. It helps us link commits with issues being tracked for easy reference. And example commit might look like this:
git commit -am "MLHR-12345 #comment Task completed ahead of schedule #resolve"
