Use lazy initialization instead of class initialization in NodeId
-----------------------------------------------------------------
Key: CASSANDRA-2953
URL: https://issues.apache.org/jira/browse/CASSANDRA-2953
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 0.8.0
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Trivial
Fix For: 0.8.3
Attachments: 0001-Use-lazy-initialization-for-NodeId.patch
The class initialization of NodeId triggers a read to a system table. When
using the class introduced in CASSANDRA-2911, this happens to be triggered even
though this is not necessary. This a a pain because when you use those classes,
you don't have to have to set reasonable values for the data_dir and
commitlog_dir in cassandra.yaml (it is a pain to have to have a cassandra.yaml
in the classpath in the first place, but that's for another ticket).
This ticket proposes using lazy initialization in NodeId to avoid that.
