Downloaded sources, build Java and .NET parts, ran examples.
There is a minor issue with .NET Core examples, compiler warning is
displayed (certainly not a blocker) [1]

I've downloaded and built the sources, run several examples.
Also, I checked several times the test
`testAtomicOnheapTwoBackupAsyncFullSync` related to the issue
discussed in a separated thread - OK.

I've checked new RC using Apache Ignite TeamCity Bot. The bot now uses
Apache Ignite V2.7.0-RC2, tested locally & deployed to the server.
PS Nikolay, thanks for sharing the link.

Re: [VOTE] Apache Ignite 2.7.0 RC2
Posted by Dmitriy Pavlov <dp...@apache.org>.
Nikolay, Igniters,
Could you please advice where can I find a staging for RC-2?
I can't find it in https://repository.apache.org/content/repositories/
Or should I reuse the old one?
https://repository.apache.org/content/repositories/orgapacheignite-1431/
Thank you in advance.
Sincerely,
Dmitriy Pavlov
