Subject Re: Ignite 2.8 Release: Time & Scope & Release manager

Dmitriy,

Please find a copy-paste from the first conversation when impactful
usability problems were reported more than a month ago:

*I played with the latest Oracle JDK 11 on Mac OS Mojave. Results are sad:*

   - *Starting a node from cmd (ignite.sh) - FAILED*
   - *Opening Ignite examples - BAD EXPERIENCE*
      - *pom.xml wasn't detected automatically, had to select it manually*
      - *was hard to start the code samples (same issue as with cmd). As a
      committer, I know how to fix it
      (https://apacheignite.readme.io/docs/getting-started#section-running-ignite-with-java-9-10-11
      <https://apacheignite.readme.io/docs/getting-started#section-running-ignite-with-java-9-10-11>),
      but most of the developers have no glue and will give up*
      - *The step above have to be repeated for every single sample*

Now, imagine that dozens of users new to Ignite go through this. Most of
them will quit after the failures above and switch to an alternate solution
- there are many choices depending on a use case.

Give me a call if it still doesn't sound convincing to you. What I would
do, considering Vladimirs's feedback, if the master is really in a bad
shape then I would release 2.8 from 2.7 and 2.8.1, 2.8.2, etc. will be
released from the master.

Denis
