解决启动hive时报错问题

一、错误

java.lang.OutOfMemoryError: Java heap space
	at java.net.ServerSocket.accept(ServerSocket.java:512)
	at org.apache.thrift.transport.TServerSocket.acceptImpl(TServerSocket.java:113)
	at org.apache.hadoop.hive.metastore.TServerSocketKeepAlive.acceptImpl(TServerSocketKeepAlive.java:39)

二、解决方法
是启动hive时，与hive相关的两个服务没有启动开，两个服务的启动命令是：

 bin/hive --service metastore &
 bin/hive --service hiveserver &
