-------------------------------------------
Summary: ZooKeeperInstance lazy load instanceId
Key: ACCUMULO-1699
URL: https://issues.apache.org/jira/browse/ACCUMULO-1699
Project: Accumulo
Issue Type: Improvement
Components: client
Affects Versions: 1.5.0
Reporter: Christopher Tubbs
Fix For: 1.6.0
I was unit testing the serialization of ZooKeeperInstance settings in a
mapreduce job, and discovered that I couldn't deserialize and construct the
ZooKeeperInstance unless the hostnames were valid and ZK was running.
It should be possible to construct an instance of ZooKeeperInstance without
trying to connect.
It is unintuitive that it immediately tries to connect to ZooKeeper when it is
constructed, instead of waiting until getInstanceId() is called.
The constructor should only construct the object... not do work.
