Dmitriy Pavlov commented on IGNITE-8430:

I've checked code and it looks good to me, in the same time there is number of suspicious
test fails, so I've retriggered these suites.

>                 URL: https://issues.apache.org/jira/browse/IGNITE-8430
>             Project: Ignite
>          Issue Type: New Feature
>    Affects Versions: 2.5
>            Reporter: Max Shonichev
>            Assignee: Anton Kalashnikov
>            Priority: Major
>             Fix For: 2.5
> Currently, user can obtain coordinator node id via JMX attribute Coordinator of TcpDiscoverySpi
OR ZookeeperDiscoverySpi MBean.
> However, to get this attribute, external utility JMX must first understand which discovery
SPI implementation is used at current grid, which is inconvenient. Would be much better if
that attribute was located in same instance no matter which Disco SPI was configured.
> Please, add String CurrentCoordinator attribute to Ignite MX bean with following meaning:
>   - for the cases, when node does not know current coordinator (e.g. getCoordinator returns
null), attribute should be empty string ''
>   - for the case, when node knows current coordinator, return following coordinator properties
formatted as string, separated by ',':
>    -- Coordinator IP address
>    -- Coordinator node ID
>    -- Coordinator node order
>    -- Coordinator Fully Qualified Domain Name
