报错Caused by: java.net.UnknownHostException: hdp6:2181: Name or service not known，这个错看了很久，因为hostname和port都是对的，卡了我很久，后来突然发现2019-10-11 20:38:54,715 INFO [Thread-6] zookeeper.ZooKeeper:438 : Initiating client connection, connectString=hdp6:2181:2181,hdp7:2181:2181,hdp8:2181:2181 sessionTimeout=120000 watcher=org.apache.curator.ConnectionState@4da855dd这句中所有的zookeeper都多了一个端口，这才意识到问题

public class ZooKeeperUtil {
private static final Logger logger = LoggerFactory.getLogger(ZooKeeperUtil.class);
private ZooKeeperUtil() {
throw new IllegalStateException("Class ZooKeeperUtil is an utility class !");
}
public static String getZKConnectStringFromHBase() {
Configuration hconf = null;
try {

hconf = (Configuration) hbaseConnClz.getMethod("getCurrentHBaseConfiguration").invoke(null);
} catch (Throwable ex) {
logger.warn("Failed to get zookeeper connect string from HBase configuration", ex);
return null;
}
final String serverList = hconf.get("hbase.zookeeper.quorum");
final String port = hconf.get("hbase.zookeeper.property.clientPort");
return StringUtils.join(Iterables.transform(Arrays.asList(serverList.split(",")), new Function<String, String>() {
@Nullable
@Override
public String apply(String input) {
return input + ":" + port;
}
}), ",");
}
}
然后翻看HBase的配置文件，之前把ip和port配置在了一起就导致重复拼接
<property>
<name>hbase.zookeeper.quorum</name>
<value>hdp6:2181,hdp7:2181,hdp8:2181</value>
</property>
所以，翻看源码得知需要拆成两个配置，如下：
<property>
<name>hbase.zookeeper.quorum</name>
<value>hdp6,hdp7,hdp8</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
然后再次启动kylin
bin/kylin.sh start发现报错，如下：
