Hi all, I am using HBase 0.90+HBASE-3789 and I want to know how to restart the cluster safely.
Basically, there are two kinds of restarts: 1. Keep the HBase cluster working while restarting the whole cluster. 2. Stop-the-world cluster restart which only ensure data safety. >From my understanding, graceful_stop.sh and rolling restart is used for kind #1. But, HBASE-3789 said it broke rolling restart. So, can anyone tell me what it broke and how to fix it to make rolling restart work? And, I can't find document about the kind #2 stop-the-world restart. Can any one point me the how-to document about it? Thanks Weihua
