I am doing a cluster upgrade to the HDP 2.2 stack. For some reason, after the upgrade HBase cannot find any regions for existing tables. I believe the HDFS file system is OK. But looking at the ZooKeeper nodes, I noticed that many (maybe all) of the regions were listed in the ZooKeeper /hbase-unsecure/region-in-transition node. I suspect this could be causing a problem. Is it safe to stop HBase and delete that node?
Thanks Brian
