Ubuntu 14.10 下Hadoop 错误集

fddfe

1 FATAL org.apache.hadoop.ha.ZKFailoverController: Unable to start failover controller. Parent znode does not exist.
　　这个错误导致启动不了DFSZKFailoverController，从而不能选举出Active Node，导致了Hadoop两个NameNode都是Standby，我是这样做的
　　停掉Hadoop所有进程，然后重新格式化Zookeeper



hdfs zkfc -formatZK
　　

2 紧接着上个问题，再重新格式化过zookeeper之后，发现yarn启动不了了

　　但是这个问题，估计还是因为zookeeper造成的，但是我没任何修改，从新启动yarn。。。竟然成功了



start-yarn.sh
　　

3 NameNode启动不了

　　我这里的错误关键是：



tried to access method com.google.common.base.Stopwatch.<init>()V from class org.apache.hadoop.hdfs.qjournal.client.IPCLoggerChannel
　　后来排查，发现是因为：com.google.common.base.Stopwatch这个类造成的，因为这个类在guava.jar中，但是这个jar包在Hadoop 中是11.0.2，但是在java_home/jre/lib/ext中还有一个是18.*，那么造成了版本不一致，所以我的解决办法是：删掉java_home/jre/lib/ext中的guava.jar
