"Hi all, I ran two Okapis by jar with cluster in two centos VMs, they can find each other by /_/discovery/nodes. But i found if kill one Okapi node, and want to restart it, will failed with NullPointException, the only way is stop both two Okapis, and then restart them. Is there any other solution? the screenshots are my stop.sh and exception log, thanks."
