Ivan Daschinskiy updated IGNITE-13577:
--------------------------------------
Description:
Proposed design:
*LN* -- node that performs graceful shutdown
*CRD* -- Leader (coordinator) of Ignite cluster
*N* -- Other nodes of Ignite cluster.
# While elected, *CRD* set watches on /<root>/ns
# *LN* create EPHEMERAL znode on /<root>/ns
# *LN* blocks stop until receive NODE_LEFT event.
# *CRD* receives notification and reset watches on /<root>/ns
# *CRD* generate NODE_LEFT event.
# *LN* receives events and continue stop process
# *CRD* on receiving all acks checks that there is no nodes on /<root>/ns and
/<root>/n
related to *LN* and remove them if they presents.
