--------------------------------------
Summary: GraphiteSink fails to re-connect to Graphite instances
behind an ELB or any other auto-scaled LB
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
Priority: Critical
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.
