pig没有使用hcatalog定位配置单元表

我使用pig访问通过hcatalog创建的表batting\u数据。在执行此操作时，我遇到一个错误，即找不到所提到的表。不过，这个击球数据表在Hive中可用。我也明白，如果没有提到数据库名称，那么就假定为默认值。
error org.apache.pig.tools.grunt.grunt-错误1115:找不到表：default.batting\未找到数据表
我已经设置了hive-site.xml，如下所示。请注意，我使用的不是metastore的远程服务器，而是mysql的本地服务器

<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>

我已经在我的.bashrc中为pig与hive和hcatalog的集成设置了以下内容。
export pig\u opts=-dhive.metastore.local=true export pig\u classpath=$hcat\u home/share/hcatalog/：$hive\u home/lib/
当清管器启动时，默认情况下将加载下面的语句。
register/home/shiva/hive-0.12.0/hcatalog/share/hcatalog/hcatalog-core-0.12.0.jar；register/home/shiva/hive-0.12.0/lib/hive-exec-0.12.0.jar；register/home/shiva/hive-0.12.0/lib/hive-metastore-0.12.0.jar；
下面是错误消息的完整日志。如有任何帮助，我们将不胜感激。谢谢。

好了，开始。。我修好了。。
我没有提到pig的opts与hive-thrift服务器的正确地址，因为pig无法连接到hive-metastore，并且找不到相应的表。改成 PIG_OPTS=-Dhive.metastore.uris=thrift://localhost:10000 使用启动hiveserver服务
$bin/hive—服务hiveserver
以上解决了这个问题，现在我可以连接Pig到Hive。谢谢
