Ivan,
Online Javadoc? Is there such a unicorn? 
Hahaha! Yes, there are some older versions (19.X, and also 20.1 Beta) but
nothing later. I don't use them for the actual descriptive writeup (which
is usually quite barren), but find them very useful to check class and
method names during migrations. And then, what's missing from the Javadoc
is usually filled in very nicely by the excellent and helpful ES folks such
as yourself, so it always ends well for me!
I find the issues on Github to be more complete, but even though, some
changes are not properly tagged:
Issues · elastic/elasticsearch · GitHubhttps://github.com/elasticsearch/elasticsearch/issues?direction=desc&labels=v0.90.8%2Cbreaking&milestone=&page=1&sort=updated&state=closed
At
https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/cluster/node/DiscoveryNodes.java
I found this useful example of iterating across the ImmutableOpenMap class:
public DiscoveryNode findByAddress(TransportAddress address) {
for (ObjectCursor<DiscoveryNode> cursor : nodes.values()) {
DiscoveryNode node = cursor.value;
if (node.address().equals(address)) {
return node;
}
}
return null;
}
Luckily, most breaking code changes are easy to fix.
Indeed, this was the case. Only one of my Java source files that use ES
(out of 110) needed to be modified. Found some snippets on github to help
with the migration. Next is to verify that it actually works, now that it
compiles. Here's my full svn diff:
