  • Hive 问题

    hive 重启连接不上

    异常信息:
    FAILED: HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
    解决方法:

    rm   metastore_db/*.lck
    

    一般情况下都可以解决,要是还不行,就把这个目录删了
    参考:
    https://stackoverflow.com/questions/22711364/java-lang-runtimeexceptionunable-to-instantiate-org-apache-hadoop-hive-metastor

    schematool -dbType mysql -initSchema 执行失败的问题

    一般就是配置文件有问题 改成这样
