Druid Historical node restart

We are upgrading from Druid 0.7.1.1 to Druid 0.8.1 and have 2 historical nodes in the cluster of 8 machines.

We have restarted one historical node as part of an upgrade and are waiting for it to come back online and be fully back into the cluster before restarting the other node to complete the upgrade.

The question we have is how can we tell when the node has completed re-reading segments and has all segments available?

Regards,

Andrew Nugent

Hi Andrew, I think we discussed this over IRC but you can use the coordinator HTTP endpoints for loadstatus?full to see if your cluster has fully recovered before restarting another historical.
