-------------------------------------
{{I would like to work on this issue. I will look into the RegionServer startup
path and the GetBootstrapNodes RPC handling, then prepare a PR if I can
reproduce the NPE. If nobody is working on it, could someone assign it to me?}}
> HRegionServer.getBootstrapNodes() NPE when GetBootstrapNodes RPC arrives
> during startup
> ---------------------------------------------------------------------------------------
>
> Key: HBASE-30099
> URL: https://issues.apache.org/jira/browse/HBASE-30099
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 3.0.0-beta-1, 2.6.5, 2.5.14
> Reporter: Nick Dimiduk
> Priority: Major
>
> {{HRegionServer.getBootstrapNodes()}} throws {{NullPointerException: Cannot
> invoke "BootstrapNodeManager.getBootstrapNodes()" because
> "this.bootstrapNodeManager" is null}} when the {{GetBootstrapNodes}} RPC
> arrives after the RPC server starts accepting connections but before
> {{preRegistrationInitialization()}} has assigned the field. Once tripped,
> every subsequent {{GetBootstrapNodes}} RPC on that instance returns the same
> NPE to the caller.
> Observed in production on a branch-2.6 cluster during a period of fleet-wide
> RS restarts, when peer RegionServers all issued bootstrap-node discovery
> against each fresh RS during its startup window. Same class of startup race
> as HBASE-28088.
