Xiaoyu Yao commented on HDDS-699:
---------------------------------
Thanks [~Sammi] for working on this. Patch v2 LGTM overall. Here are some
comments. I will add more comments on unit test later.
DatanodeDetails.java
Line 220: is there a reason to remove the compareTo @Override annotation?
Node.java
Line 45: NIT: typo "contamination" -> "concatenation"
Line 72: do we really want to allow setLevel() explictly or it is for testing
only? This may mess up with the
actual level that is set up via setParent().
InnerNode.java
Line 89: does the leafIndex count the excludedNodes?
InnerNodeImpl.java
Line 295-301: can we document this in the getLeaf() API?
NodeSchema.java
Line 80-90: maybe we can add a build class to help reducing the # of
constructors.
Line 102: do we assume case sensitive for the network path and prefix here?
NodeSchemaLoader.java
Line 126/128/130/186/187: NIT can we get these perdefined tag name defined as
static const?
NodeSchemaManager.java
Line 98: can we add javadoc for completePath()?

> Traditionally this has been implemented in Hadoop via script or customizable
> java class. One thing we want to add here is the flexible multi-level support
> instead of fixed levels like DC/Rack/NG/Node.
