[jira] [Commented] (SENTRY-1872) Check if a Sentry server is accessible before connecting to it

    [ https://issues.apache.org/jira/browse/SENTRY-1872?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16117557#comment-16117557 ] 

Alexander Kolbasov commented on SENTRY-1872:
--------------------------------------------

Why would check for a server being reachable be any better then just an attempt to connect to it? What extra value would it add to compensate for the extra latency?

> For Sentry HA, if one of the server is unreachable for any reason, we would still try to connect to it, and only switch to other server after a timeout exception is thrown. We should instead check if the server is reachable first before we try connecting to it
