Today, we will discuss about “What is HA Implementation of Node” in Big data testing and what are the test-scenarios for HA testing and other points can be considered
In simple words, by creating one more standby replica node of the Working node and can be use if Working node downs due to any reason. If we have Replica node, this would ensure no down time and very minimum jobs failure in case hardware fails/any outage. Both nodes should be same as hardware, software and configuration wise except IP and Hostname are different to identify.
Work in Progress….
