Modified cluster.yaml to support num servers per group #5037
Conversation
Modified cluster.yaml to support specifying number servers per group for compactors, sservers, and tservers. This was supported previously, but the implementation was different and the information was not as tightly coupled in the yaml file. Closes apache#5032

These changes are really nice. I only looked at the java code and java test in detail though. Did not look at the shell code changes in detail.

Would a 2.1 cluster.yaml file fail to parse w/ a clean message w/ these changes? |
I don't think the compactor/sserver/tserver sections would work. I can test with a 2.1 config and make sure a good error is thrown. |

Should this also have a compaction-coordinator section?

I don't think so, scan servers and external compactions are optional and experimental in 2.1. This is a minimal config for 2.1

Tested locally.
Specified different groups and number of servers per group.
stop and start commands worked.
Verified service counts via ./accumulo admin serviceStatus --noHosts
