I've been trying to get cross cluster to work between two geographically remote clusters. I've gotten it to work but frequently, it just stops working. Querying _remote/info and remote indices hang indefinitely. But after some time (I don't know the length since I usually go do something else), it works again.
Is there some sort of logging that I can look at to see what is happening?
I'm running ES 5.6.2 in both clusters. Cluster A can talk to Cluster B on both the http transport and the es transport port. Cluster B can NOT talk to Cluster A, though. Only Cluster A is set up for cross cluster, though, so I believe that should not be an issue.
