> When a failure occurs in the execution stack it will be logged up to 6 times in the server logs.
> For example trying to query a bad json (extra ':') file will cause the following events:
> - ScanBatch.next() logs a debug message "Failed to read the batch. Stopping..." and calls FragmentContext.fail()
> - FragmentContext.fail() logs an error message "Fragment Context received failure -- Fragment: "
> - FragmentExecutor.run() calls internalFail() and logs an error message when calling ErrorHelper.logAndConvertError()
>   "Error <error id>: <error message>"
> - Foreman.close() calls ErrorHelper.logAndConvertError() which logs an error message "Error <error id>: <error message>"
> - FragmentExecutor.closeOutResources() will throw a RuntimeException because it contains a non null deferredException (the original exception). This exception is caught in run() and a warning message is logged "Error while initializing or executing fragment"
> - FragmentExecutor.run() calls FragmentContext.fail() when it catches the RuntimeException which will log an error message "Fragment Context received failure -- Fragment: "
