Hi All, 1. If my discovery type is ec2, which of the following settings are actually in effect? discovery.zen.ping\_timeout: 60s discovery.zen.fd.ping\_timeout: 60s discovery.ec2.ping\_timeout: 60s discovery.ec2.fd.ping\_timeout: 60s 1. what's the difference between discovery.zen.ping\_timeout and discovery.zen.fd.ping\_timeout? Is one just a typo that got propagated on the web? Thanks in advance, Jason -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

To answer my own question #2: discovery.zen.ping\_timeout: timeout for master selection. discovery.zen.fd.ping\_timeout: timeout for fault detection. So question #1 is now: If discovery type is set to ec2, which is correct? discovery.ec2.fd.ping\_timeout or discovery.zen.fd.ping\_timeout?

The following timeouts are set in Zen Discovery: discovery.zen.initial\_state\_timeout (30s) - waiting for the initial state set by discovery discovery.zen.publish\_timeout (30s) - waiting for publishing state Node and master detection: discovery.zen.ping\_interval (1s) - interval for pinging discovery.zen.ping\_timeout (30s) - waiting for response discovery.zen.ping\_retries (3) - how many retries before timeout Node and master fault detection: discovery.zen.fd.ping\_interval (1s) - interval for pinging discovery.zen.fd.ping\_timeout (30s) - waiting for response discovery.zen.fd.ping\_retries (3) - how many retries before timeout The "discovery.zen.fd" component settings can override the "discovery.zen" settings, for example, if you want to wait only a short time for detecting new nodes before timeout (faster node startup), but a longer time for non-responsive nodes before a faulty node is reported. In most cases, you do not need to set timeouts in "discovery.zen.fd", it will simply inherit from "discovery.zen" settings.
