------------------------------------

             Summary: For very large files, content viewer fails with OutOfMemoryError, screen looses look and feel
                 Key: NIFI-11153
                 URL: https://issues.apache.org/jira/browse/NIFI-11153
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Nissim Shiman


For very large files, content viewer fails with 
HTTP ERROR 500 java.lang.OutOfMemoryError: Java heap space

The nifi gui loses its "look and feel" and the screen goes white
with the additional details:

URI:    /nifi-content-viewer/
STATUS:    500
MESSAGE:    java.lang.OutOfMemoryError: Java heap space
SERVLET:    ContentViewerController
CAUSED BY:    java.lang.OutOfMemoryError: Java heap space
Caused by:
java.lang.OutOfMemoryError: Java heap space

To recreate:
GenerateFlowFile -> funnel
where GenerateFlowFile's filesize is 100MB

then view file on output queue

(Issue was also seen with json file of 100MB)

Possible solution maybe to check for file over a certain size before attempting to process for viewing.
