Are there any Accumulo system table that are offline (root, metadata)? Is there a manager (master) process available? What is the manager log saying?

The datanode and tserver share the same hosts. In the event that one rack goes down, will accumulo be still functioning (after hdfs data replication)? What I am finding is accumulo monitor is up and showing half the tablets are unreachable, I can get to accumulo shell but I can’t scan any tables. From the log I can see there are some locks in zookeeper. But overall accumulo, although up, is not usable ☹ Is there any way around it? -S
