@mcgilman With the current state of the commit, if a processor previously
didn't have `executionNodeRestricted` and the `executionNode` was `ALL`, it
will still be hidden. Now I understand that shouldn't be the case. Thanks for
the clarification so I think the following will address this:
var getExecutionNodeOptions = function (processor) {
return [{
text: 'All nodes',
value: 'ALL',
description: 'Processor will be scheduled to run on all nodes',
disabled: processor.executionNodeRestricted === true
}, {
text: 'Primary node',
value: 'PRIMARY',
description: 'Processor will be scheduled to run only on the
primary node',
disabled: !nfClusterSummary.isClustered() &&
processor.config['executionNode'] === 'PRIMARY'
}];
};
And changing the code to show when `execution-node-options` gets shown in
the UI to the following:
if ((nfClusterSummary.isClustered() && executionNodeRestricted !==
true) ||
(!nfClusterSummary.isClustered() && executionNode === 'PRIMARY') ||
(executionNodeRestricted === true && executionNode === 'ALL')) {
$('#execution-node-options').show();
} else {
$('#execution-node-options').hide();
}
There are two much checks in the `if` but I think they are needed to
address this. If that can be optimized or modified, do let me know.

> There are Processors that are known to be problematic if run from multiple
> nodes simultaneously. These processors should be able to use a
