We run elasticsearch 1.7 and the cluster has around 342 nodes. I am trying to set the search threadpool size to 14 and the setting is applied correctly, meaning GET /_cluster/settings reflects the new values but the in /_nodes/stats the vaue of "thread_pool.search.threads" is defaulted to 13 form majority of the host. Only around a 100 hosts are getting the new value (14)
Any points on how can I debug this issue? seems like nodes are not pooling the latest config from master
Hey Mark, I figured out the issue. It was related to the new plugin we integrated for elasticsearch metrics. And yes, Upgrading is the plan !
