[jira] [Updated] (IGNITE-19896) Incorrect leader in the RaftGroupServiceImpl

["Vadim Pakhnushev (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-19896?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vadim Pakhnushev updated IGNITE-19896:
--------------------------------------
    Description: 
When sending a message to the random node either in the refreshLeader or in the 
sendWithRetry after the error, the peer to which the message was sent gets assigned to the {{leader}} field before the message response is handled. If during this period another thread would call {{{}leader(){}}}, it could get random peer instead of a leader.

Also the {{leader()}} call returns incorrect result even at the time of the {{RaftGroupEventsListener.onLeaderElected}} callback.
