猪没有使用Hcatalog找到Hive Table

标签： hive apache-pig hcatalog

我使用PIG访问通过HCatalog创建的表batting_data。在这样做时，我面临一个错误，说没有找到提到的表。但是，这个batting_data表可用于HIVE。我也明白，如果没有提到数据库名称，则假定为默认值。

错误org.apache.pig.tools.grunt.Grunt - 错误1115：找不到表：找不到default.batting_data表

  1. 我已经设置了hive-site.xml，如下所示。请注意我没有使用远程服务器用于Metastore，而是使用本地服务器mysql 

    <configuration>
<property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://localhost/metastore?createDatabaseIfNotExist=true</value>
        <description>the URL of the MySQL database</description>
</property>

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

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

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

<property>
        <name>hive.hwi.listen.host</name>
        <value>0.0.0.0</value>
</property>
<property>
        <name>hive.hwi.listen.port</name>
        <value>9999</value>
</property>
<property>
        <name>hive.hwi.war.file</name>
        <value>lib/hive-hwi-0.12.0.war</value>
</property>

<property>
        <name>hive.metastore.local</name>
        <value>true</value>
</property>

  2. 我在.bashrc中设置了以下内容，用于与HIVE和HCATALOG的PIG集成。

    export PIG_OPTS = -Dhive.metastore.local = true export PIG_CLASSPATH = $ HCAT_HOME / share / hcatalog / ：$ HIVE_HOME / lib /

  3. 当PIG启动时，GRUNT shell将默认加载以下语句。

    注册/home/shiva/hive-0.12.0/hcatalog/share/hcatalog/hcatalog-core-0.12.0.jar; 注册/home/shiva/hive-0.12.0/lib/hive-exec-0.12.0.jar; 注册/home/shiva/hive-0.12.0/lib/hive-metastore-0.12.0.jar;

    4. 错误消息的完整日志如下所示。任何帮助解决这个问题将不胜感激。感谢。

1 个答案:

答案 0 :(得分：2)

好的，这就是..我修好了..

  1. 我没有提到具有正确的HIVE THRIFT服务器地址的PIG_OPTS，因为哪个PIG无法连接到HIVE Metastore并找不到其他表。 已将其更改为PIG_OPTS=-Dhive.metastore.uris=thrift://localhost:10000

  2. 使用

    启动HIVESERVER服务

    $ bin / hive --service hiveserver

    3. 以上解决了这个问题，现在能够将PIG连接到HIVE。 感谢
