運行配置單元腳本“ am_stats_analyzer_163” cassandra的WSO2 BAM錯誤

Question

我在2個不同的虛擬機上運行APIM和BAM，並在BAM上運行外部Cassandra。

error when executing a hive script (am_stats_analyzer_163) 我執行蜂巢腳本時出現“執行蜂巢腳本時錯誤（am_stats_analyzer_163）

這是完整的錯誤跟蹤：

我用於cassandra的用戶名​​和密碼是默認的（admin / admin），它們在[BAM_HOME] /repository/conf/etc/cassandra-auth.xml和[BAM_HOME] / repository / conf中進行了定義。 /datasources/master-datasources.xml

您知道可能是什么問題嗎？

永恆的MySQL數據源配置：

<datasource>
            <name>WSO2AM_STATS_DB</name>
            <description>The datasource used for getting statistics to API Manager</description>
            <jndiConfig>
            <name>jdbc/WSO2AM_STATS_DB</name>
        </jndiConfig>
        <definition type="RDBMS">

            </configuration>
        </definition>

api-manager.xml配置：

 <Enabled>true</Enabled>

    <ThriftPort>7611</ThriftPort>

    <DataSourceName>jdbc/WSO2AM_STATS_DB</DataSourceName>

這些表也是在MySQL數據庫內部創建的：

Answer 1

請確保已使用正確的BAMServerURL和ThriftPort配置了api-manager.xml，這些文件位於/repository/conf/api/manager.xml中

<!-- Enable/Disable the API usage tracker. -->
<Enabled>true</Enabled>  
    <PublisherClass>org.wso2.carbon.apimgt.usage.publisher.APIMgtUsageDataBridgeDataPublisher</PublisherClass>
    <ThriftPort>7612</ThriftPort>
    <BAMServerURL>tcp://localhost:7612/</BAMServerURL>
    <BAMUsername>admin</BAMUsername>
    <BAMPassword>admin</BAMPassword>
    <!-- JNDI name of the data source to be used for getting BAM statistics. This data source should
        be defined in the master-datasources.xml file in conf/datasources directory. -->
    <DataSourceName>jdbc/WSO2AM_STATS_DB</DataSourceName>

</APIUsageTracking>

Answer 2

由於SQL異常，似乎RDBMS相關的Hive查詢出現問題。 請重新檢查刪除“插入覆蓋...”查詢后，Hive腳本是否運行。 如果是這種情況，請重新檢查腳本的該部分。 在重新執行查詢之前，請手動刪除RDBMS表（例如，使用H2數據庫客戶端），並像在Hive腳本頂部的查詢一樣添加“ drop table ...”，以清理RDBMS包裝的Hive表。

Answer 3

嘗試在data-bridge-config.xml中將hostName設置為0.0.0.0：

<thriftDataReceiver>
    <hostName>0.0.0.0</hostName>
        <port>7611</port>
        <securePort>7711</securePort>
</thriftDataReceiver>

並在cassandra.yaml中設置rpc_address：0.0.0.0。

該錯誤與不正確的主機/端口有關。
