I am having a cluster like below
- 3 Hbase Master (1 Active & 2 standby) - 4 Region Servers - 4 Data Nodes - 1 Primary & 1 Secondary Name Node - 3 Journal Node - 4 Nodemanager - 3 Resource Manager (1 Active & 2 standby) Can someone let me know how can I plan a rolling upgrade of the above cluster with minimum downtime? I am not able to locate these on the documentations. - Hadoop - 2.6.0 - Yarn - 2.6.0 - Hbase - 1.2.0
