But, a area server that connects to an ensemble managed with a special configuration is going to be subjected that ensemble’s maxSessionTimeout. So, While HBase might propose working with 90 seconds, the ensemble may have a max timeout reduce than this and it will choose precedence. The present default maxSessionTimeout that ZK ships with is 40 seconds, which happens to be lower than HBase’s.
