java.lang.RuntimeException：无法实例化org.apache.hadoop.hive.metastore.HiveMetaStoreClient [英] java.lang.RuntimeException:Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

问题描述

我已将Hive配置为链接： http://www.youtube.com/watch?v=Dqo1ahdBK_A ，但在Hive中创建表时出现以下错误。我正在使用hadoop-1.2.1和hive-0.12.0。

  hive>创建表员工（emp_id int，名称字符串，工资双倍）; 
 FAILED：执行错误，从org.apache.hadoop.hive.ql.exec.DDLTask返回代码1。 java.lang.RuntimeException：无法实例化org.apache.hadoop.hive.metastore.HiveMetaStoreClient 
  

解决方案

看起来像您的Metastore问题。如果您正在使用默认配置单元metastore嵌入式德比。如果出现异常退出，锁定文件将在那里。如果您删除该锁文件，此问题将被解决



$ $ p $ r $ metastore_db / *。lck

code>

I have configured my Hive as given on link: http://www.youtube.com/watch?v=Dqo1ahdBK_A, but I am getting the following error while creating a table in Hive. I am using hadoop-1.2.1 and hive-0.12.0.

hive> create table employee(emp_id int,name string,salary double);
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

解决方案

Looks like problem with your metastore. If you are using the default hive metastore embedded derby. Lock file would be there in case of abnormal exit. if you remove that lock file this issue would be solved

rm   metastore_db/*.lck
