Parameter/Field

Comments/Description

Listener Port

Enter the listener port for BI Server.

JMX Port

Enter the JMX port for BI Server health monitoring.

Work Directory

Enter the directory location on HDFS, where BI Server has access permissions.

Memory Configuration Mode

By default, the Auto mode is selected. In Auto Mode, calculations are performed automatically by the system internally.
In Manual Mode, you can manually provide memory values as needed.
NOTE: The Maximum Heap Memory and Analytical Store Max Memory options are enabled only when you set the memory configuration in the Manual mode.

Maximum Heap Memory

Enter the maximum memory available for BI Server.

Analytical Store Max Memory

Specify analytical store max memory for querying in GB.

Additional Java Options

Use this to define custom Java properties for your BI Server.

Parameter/Field

Comments/Description

Thrift Listener Port

Enter the thrift listener port for Query Engine

JMX Port

Enter the port for Query Engine health monitoring.

Memory Configuration Mode

By default, the Auto mode is selected. In Auto Mode, calculations are performed automatically by the system internally. In the Manual Mode, you can manually provide memory values as needed.

NOTE:

• The Maximum Heap Memory, Analytical Store Max Memory for Querying, Analytical Store Max Memory for Processing, and Configure Concurrent Processing Task options are enabled only when you set the memory configuration in the Manual mode.

• If you set the memory configuration in the Manual mode, the Configure Concurrent Processing Task option can be enabled as Auto or Manual as needed.

Maximum  Heap Memory

Enter the maximum memory for Query Engine.

Off Heap Memory

Enter the maximum memory available to Query Engine for cuboid caching.

Additional Java Options

Use this to define custom Java properties for your Query Engine.

Use YARN

Select this checkbox to launch Query Engines using the Hadoop application master.

NOTE: If this option is not selected, you MUST mention the Query Engine nodes at the time of node mapping . Also, you can configure multiple instances of Query Engine.

YARN Job Name

Provide the YARN job name on which the application has to be submittedAnalytical Store Max Memory for Querying

Specify analytical store max memory for querying in GB.

Analytical Store Max Memory for Processing

Specify analytical store max memory for processing in GB.

Configure Concurrent Processing Task Count

By default, the Auto mode is selected. If you select the Manual mode, specify the number of nodes to be used for concurrent processing task count.

YARN Queue Name

Provide the YARN queue name on which the application has to be submitted.

Application Master Cores and Memory 

Enter virtual cores to be used by Application Master

Enter memory to be used by Application Master

Application Master Log Path 

Provides the logs of the Application Master

Application Master Schedule 

Select a day(s) and time to restart the Application Master

Query Engine Operation Mode

Select the Count Based or Host Based option.

Query Engine Host Names

Enter a comma-separated list of hostnames where the YARN-based Query Engine will be deployed. Follow the Hostnames by instance count separated by a colon.

Example: host-1:1,host-2:3

Query Engine Instance Count

Enter the number of Query Engine instances to be launched.

Container Cores and Memory

Enter the number of virtual cores to be used by Kyvos Query Engine.

Enter the memory to be used by Kyvos Query Engine.

Query Engine Log Path

Enter the path for saving Query Engine logs. Ensure that the path exists on data nodes, and the user (with which YARN containers are launched) has write permissions on this path.

Logs Sync Interval

Enter the time interval for syncing Query Engine logs on HDFS.

YARN Job Name

Enter a name for the YARN job.

Enable Query Engine Auto Scaling

Select this check box to enable automatic scaling of the Kyvos Query Engine.

Query Engine Minimum Instance Count

Provide a count of the number of Query Engines that should be running in scale-down mode.

Query Engine Minimum Instance Names

Provide a comma-separated list of hostnames on which Query Engines will be running in scale-down mode. This is displayed only when auto-scaling of Query Engines is enabled.

Query Engine Instance Names

Select the Query Engine instance to be used from the list. This is displayed only when auto scaling of Query Engines is enabled.

Additional Query Engine Instance Names

Enter additional minimum Query Engine hostnames (if any). This is displayed only when auto scaling of Query Engines is enabled.

Scale Up Time

Enter the time in HH:MM format at which the Query Engine will be scaled up. Ensure that the correct time zone is displayed.

Scale Down Time

Enter the time in HH:MM format at which the Query Engine will be scaled down. Ensure that the correct time zone is displayed.

Application Master Restart Style

If Hadoop is running in secure mode, select Never or Fix Schedule so that the Application Master can get the Kerberos ticket.

If selecting the Fix Schedule option, select the time and days to restart the Application Master automatically.
