Hi all, I have a setup with 67 region servers. 29 Dec one system had to be shut down to have EMM module swapped out - which took one work day. Host was back online 30 Dec.
My HBASE is very basic so I appreciate your patience. My understanding of the defaults that are setup is that a major compaction should occur every 7 days. Moreover, do I assume that more extensive balancing may occur after this happens? When I check (via hbase master UI) the status of HBASE, I see the following: ServerName Start time Last contact Version Requests Per Second Num.

Should I initiate some kind of rebalancing? Thanks in advance. M
