Mona Chitnis updated OOZIE-1186:
--------------------------------

    Attachment: OOZIE-1186.patch

WIP patch to free up memory resources used during image generation, and i/o resources in servlet.

Conducted memory profiling of Oozie server JVM run with and without the patch and saw the difference.
Need to think about unit tests for the same.

> The Job DAG visualization loads an image into memory to be streamed on outputstream. However, it does not free up memory and I/O resources leading to 'Out of Java heap space' errors.
