(Updated July 22, 2015, 6:29 p.m.) Review request for Aurora and Zameer Manji. Bugs: AURORA-1405 https://issues.apache.org/jira/browse/AURORA-1405 Repository: aurora Description ------- Added fix for Aurora client to connect to correct zookeeper-hosts address/port pairs. When more than one zookeeper host was specified in the clusters.json file, only the last host was accessed through the specified zk_port. The client would attempt to connect to all other zookeeper hosts using the default port (2181). For example, in clusters.json: [{ "name": "<my_cluster>", "zk": "host1.domain.com,host2.domain.com,host3.domain.com", "zk_port": 2626, "scheduler_zk_path": "/cluster/aurora/scheduler", "slave_run_directory": "latest" } ... ] I found that the client would attempt to access the zk hosts addresses host1.domain.com:2181, host1.domain.com:2181, and host3.domain.com:2626. Thus, the "zk_port" attribute would only update the last host in the host string-list. This change allows the client to properly connect to multiple zookeeper hosts using a port other than the specified port. Note, that the KazooClient accepts a comma-separated string of hosts.

Then verified that all hosts are now accessed through the correct port, not just the default (port 2181). Also viewable by Aurora client INFO logs. Thanks, Zane Silver
