Question

我有5个节点的hadoop集群正在运行。
Hive运行正常，可以创建表，添加数据等然后尝试重新启动所有5个节点，现在Hive无法启动。
使用MySql作为Metastore。可能是什么问题以及如何解决它？尝试启动hive时记录日志：

要解决此问题，请通过在/etc/spark/conf/hive-site.xml下添加以下属性，将本地Hive Metastore用于Spark Thrift Server：

 <property>
 <name>hive.metastore.uris</name>
 <value>thrift://localost:9083</value> 
 </property>
