Hi, I have two questions:
1. In the first part of my pipeline using Flink DataStreams processing graph edges, I'm filling up Hashmap. In it goes a vertex id and the partition this vertex is assigned to. Later in my pipeline I want to query this Hashmap again, to see in which partition exactly I can find a specific edge based on which partitions its two vertices are assigned to. What is the best way to do this? I keep getting Nullpointer exceptions. 2. Is there a good way to retrieve a single value at some point in my pipeline, and then make it globally available? I was using static, but found that this led to a Nullpointer exception when executing Flink standalone. Weirdly enough it worked fine in my Intellij. All help very appreciated!
