-------------------------------------
Summary: Improve PerClientRandomNonceGenerator
Key: HBASE-15702
URL: https://issues.apache.org/jira/browse/HBASE-15702
Project: HBase
Issue Type: Improvement
Reporter: Hiroshi Ikeda
Priority: Trivial
PerClientRandomNonceGenerator can be exposed to all the threads via the static
field ConnectionManager.nonceGenerator, but PerClientRandomNonceGenerator uses
Random, which should be ThreadLocalRandom or something. (See javadoc of Random.)
Moreover, ConnectionManager creates or refers the singleton instance of
PerClientThreadLocalRandom with a lock or volatile, but it should be created as
a static final field in PerClientThreadLocalRandom itself, and the creation
will be postponed until the field is actually refereed and the class is being
initialized.
The same can be said for ConnectionManager.NoNonceGenerator.
