You can extend the <a href="https://svn.wso2.org/repos/wso2/carbon/platform/branches/4.0.0/components/analytics/org.wso2.carbon.analytics.hive/4.0.5/src/main/java/org/wso2/carbon/analytics/hive/extension/AbstractHiveAnalyzer.java" rel="nofollow">AbstractHiveAnalyzer</a> and write you own class which executes the query and set the hive conf value, similar to this <a href="https://svn.wso2.org/repos/wso2/carbon/platform/branches/4.0.0/components/stratos/usage/org.wso2.carbon.usage.summary.helper/1.0.0/src/main/java/org/wso2/carbon/usage/summary/helper/HourlyServiceStatsSummarizerHelper.java" rel="nofollow">summarizer</a>. Here you can see the execute() method should be implemented and this will be called by BAM. Here you can add your preferred query and assign the hive conf with 'setProperty("your_hive_conf", yourResult.string());'. You can build your java application as typical '.jar' file or osgi bundle. If you have packaged as just a '.jar' file, then you should place the jar in $BAM_HOME/repository/components/lib. If you packaged the application as osgi bundle, then place the file in $BAM_HOME/repository/components/dropins folder. And restart BAM server. And finally in your hive script that you add in BAM, you should include you extended class as 'class your.package.name.HiveAnalyzerImpl;', so that BAM will run the execute() method which you have implemented in your class and your hive conf will be set. And then, value you have set for your hive conf can be used in the hive script as ${hiveconf:your_hive_conf}. Hope this helps.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
