应用场景

搭建了hadoop伪分布式集群，并且在其上搭建了hive环境，hive运行报HiveMetaStoreClient错误。

解决办法

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

修改hive-site.xml，将value修改为false即可！

  <property>       
    <name>hive.metastore.schema.verification</name>      
    <value>false</value>        
    <description>        Enforce metastore schema version consistency.        True: Verify that version information stored in metastore matches with one from Hive jars.  Also disable automatic              schema migration attempt. Users are required to manully migrate schema after Hive upgrade which ensures              proper metastore schema migration. (Default)        False: Warn if the version information stored in metastore doesn't match with one from in Hive jars.
