haadmin should have configurable timeouts for failover commands
---------------------------------------------------------------
Key: HDFS-3072
URL: https://issues.apache.org/jira/browse/HDFS-3072
Project: Hadoop HDFS
Issue Type: Improvement
Components: ha
Affects Versions: 0.24.0
Reporter: Philip Zeyliger
The HAAdmin failover could should time out reasonably aggressively and go onto
the fencing strategies if it's dealing with a mostly dead active namenode.
Currently it uses what's probably the default, which is to say no timeout
whatsoever.
{code}
/**
* Return a proxy to the specified target service.
*/
protected HAServiceProtocol getProtocol(String serviceId)
throws IOException {
String serviceAddr = getServiceAddr(serviceId);
InetSocketAddress addr = NetUtils.createSocketAddr(serviceAddr);
return (HAServiceProtocol)RPC.getProxy(
HAServiceProtocol.class, HAServiceProtocol.versionID,
addr, getConf());
}
{code}
