Jing Zhao commented on HDFS-5066:
---------------------------------
bq. What do you mean by "make the tool continue the visualization based on the
last time result"?
Here I mean after visualizing the first 500 nodes, we can continue the
visualization for the remaining nodes (maybe starting from some specific node
that has been visualized). But this is a very hard-to-define functionality and
also difficult to implement.
So for now maybe we can first move the visualization functionality to
SnapshotTestHelper, so that developers can use it for their unit test debugging
(just like we use the dumpTree method before)? We can think more about how to
expose this feature to outside as the next step.
