Start HBase cluster with more than one regionserver. > 2. Create a table with precreated regions. (lets say 15 regions) > 3. Make sure the regions are well balanced. > 4. Restart all the Regionservers process at once across the cluster, except > HMaster process > 5. After restarting the Regionservers, successfully will connect to the > HMaster. > *Bug:* > But no regions are assigning back to the Regionservers. > *Master log shows as follows:* > {noformat} >
