Use the Network Time Protocol (NTP) with HBase
Ensure that that the clocks on all the cluster members are sychronized for your cluster to function correctly. You must configure NTP to synchronize the clock.
Using NTP and DNS ensures that you won’t run into odd behaviors when one node A thinks that the time is tomorrow and node B thinks it’s yesterday. You will also prevent situations where the master node tells node C to serve a region but node C doesn’t know its own name and doesn’t answer.
- Run NTP or another clock synchronization mechanism on your cluster.
- Verify that the system time is sychronized across your cluster nodes.
