Question

我使用hive-0.9.0和mysql作为Metastore。我得到一个例外：

hive> show tables;
FAILED: Error in metadata: org.apache.thrift.transport.TTransportException:java.net.SocketTimeoutException:Read timed out

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask 
Error in metadata: MetaException(message:Could not connect to meta store using any of the URIs provided)

任何指示都会有所帮助。

此致 Neeraj

Answer 1

您是否配置了网址＆amp; Metastore的凭证是否正确？您是否尝试通过

重新启动Metastore服务？

hive --service Metoreore

Answer 2

请检查您的配置单${HIVE_HOME}/conf/hive-site.xml

hive mysql配置示例：

<property>
  <name>javax.jdo.option.ConnectionURL</name>
  <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionDriverName</name>
  <value>com.mysql.jdbc.Driver</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionUserName</name>
  <value>hive</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>hive</value>
</property>

Answer 3

转到hive / hcatalog / sbin

./ hcat_server.sh

这应该有帮助

hive元数据中的错误：org.apache.thrift.transport.TTransportException：java.net
