-------------------------------------
Summary: Make the tables recover on the same assignments on
different nodes
Key: IGNITE-20993
URL: https://issues.apache.org/jira/browse/IGNITE-20993
Project: Ignite
Issue Type: Improvement
Reporter: Denis Chudov
*Motivation*
Currently the following is possible:
* node A performs the recovery on revision _x_ and in case of absence of
stable assignments calculates the assignments from data nodes for this revision;
* node B is doing the same for recovery revision _y_ which is not equal to
{_}x{_}.
As a result, they can start partitions for different assignments which are not
consistent, and this can lead to side effects like unavailability of the
majority for some partitions.
*Definition of done*
The multiple nodes performing recovery always start partitions for assignments
calculated for the same revision.
*Implementation notes*
The common revision for different nodes in this case can be revision on which
the table was created, this revision can be saved to meta storage under the
special key.
