After enabling the Data Integration Service on GRID, the DIS fails to start on one of the Nodes.
Problem Description
No errors are reported in the DIS log, however the Domain log shows the following:

No errors are reported in the DIS log, however the Domain log shows the following:

We see the DIS starting on both nodes, but then fails on Node_02 in this example.  The JVM options for Node_02 show the Maximum Heap Size set to -Xmx2048 and JVM options for Node_01 show the Maximum Heap Size set to -Xmx1024M.
Cause
 The Maximum Heap Size set for Node_02 is missing the 'M' after the value 2048.
Solution
- From the Admin Console, choose the Data Integration Service - Processes tab - each Node will have its own list of settings.

- Click on the Node which the DIS is failing on (in this example Node_02).  Under the Advanced Properties section, update the Maximum Heap Size to include the 'M', example 2048M.  
- Click on the Properties tab, Disable the DIS and then Enable the DIS again.
