Duo Zhang commented on HBASE-20784:
-----------------------------------
I would say that, the only place we use the string style version is on the
master ui. At all other places, we just the int version number in
ServerManager. So if you think this will introduce so many problems, then
probably you have already hit the issues but you do not know...
The intention here is that, we want to remove the RegionServerTracker in the
future. IIRC, there is a issue that if an RS crashed after calling
RegionServerStart but before put up a node on zk, then it will leave there
forever...
Let me find a way to fix it. Do not want to poll the RegionServerTracker back...
Thanks.
> Will lose the SNAPSHOT suffix if we get the version of RS from ServerManager

> In HBASE-20722 we removed the usage of RegionServerTracker when getting
> information for region server. And version in server manager is a int, and we
> convert it to a String when displaying it on the master ui, so we will lose
> the SNAPSHOT suffix. Not a big one as this is not a problem for normal
> releases. Open a issue for it.
