> YARN-9264 accidentally introduced a bug in FpgaDiscoverer. Sometimes {{currentFpgaInfo}} is not set, resulting in an NPE being thrown:
> {noformat}
> 2019-06-03 05:14:50,157 INFO org.apache.hadoop.service.AbstractService: Service NodeManager failed in state INITED; cause: java.lang.NullPointerException
> java.lang.NullPointerException

> at org.apache.hadoop.yarn.server.nodemanager.NodeManager.main(NodeManager.java:942)
> {noformat}
> The problem is that in {{FpgaDiscoverer}}, we don't set {{currentFpgaInfo}} if the following condition is true:
> {noformat}
> if (allowed == null || allowed.equalsIgnoreCase(
> YarnConfiguration.AUTOMATICALLY_DISCOVER_GPU_DEVICES)) {
> return list;
> } else if (allowed.matches("(\\d,)*\\d")){
> ...
> {noformat}
> Solution is simple: initialize it in both code-paths.
> Unit tests should be enhanced to verify that it's set properly.
