hive启动一些错误记录

Posted 2020-09-26 呢喃的歌声

java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMeta

原因：因为没有正常启动Hive 的 Metastore Server服务进程。 
解决方法：启动Hive 的 Metastore Server服务进程，执行如下命令：

hive --service metastore & [1] 52460 Starting Hive Metastore Server SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/root/hadoop/hadoop-2.6.0/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/root/hadoop/apache-hive-0.14.0-bin/lib/hive-jdbc-0.14.0-standalone.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

 

hive Specified key was too long; max key length is 767 bytes

解决方法：

mysql > alter database hive character set latin1;

再在Hive里创建表已经ok了
