> Key: SPARK-22030
> URL: https://issues.apache.org/jira/browse/SPARK-22030
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.2.0
> Reporter: Alex Mikhailau
> Assignee: Alex Mikhailau
> Priority: Minor
> Fix For: 2.3.0

> Upgrade codahale metrics library so that Graphite constructor can re-resolve hosts behind a CNAME with re-tried DNS lookups. When Graphite is deployed behind an ELB, ELB may change IP addresses based on auto-scaling needs. Using current approach yields Graphite usage impossible, fixing for that use case
> Upgrade to codahale 3.1.5
> Use new Graphite(host, port) constructor instead of new Graphite(new InetSocketAddress(host, port)) constructor
> This are proposed changes for codahale lib - dropwizard/metrics@v3.1.2...v3.1.5#diff-6916c85d2dd08d89fe771c952e3b8512R120. Specifically, https://github.com/dropwizard/metrics/blob/b4d246d34e8a059b047567848b3522567cbe6108/metrics-graphite/src/main/java/com/codahale/metrics/graphite/Graphite.java#L120
