You can install Kudu through the Cloudera Manager installation wizard, using either parcels or packages. For instructions, see Cloudera Installation Guide.

For instructions on upgrading Kudu using parcels or packages, see Upgrading CDH.

If Kudu crashes, you can use Cloudera Manager to generate a core dump to get more information about the crash.

1. Go to the Kudu service.
2. Click the Configuration tab.
3. Search for core dump.
4. Check the checkbox for the Enable Core Dump property.
5. (Optional) Unless otherwise configured, the dump file is generated in the default core dump directory, /var/log/kudu, for both the Kudu master and the tablet servers.
   • To configure a different dump directory for the Kudu master, modify the value of the Kudu Master Core Dump Directory property.
   • To configure a different dump directory for the Kudu tablet servers, modify the value of the Kudu Tablet Server Core Dump Directory property.
6. Click Save Changes.

In a Cloudera Manager deployment, once the Kudu service is installed, Impala will automatically identify the Kudu Master. However, if your Impala queries don't work as expected, use the following steps to make sure that the Impala service is set to be dependent on Kudu.

1. Go to the Impala service.
2. Click the Configuration tab.
3. Search for kudu.
4. Make sure the Kudu Service property is set to the right Kudu service.
5. Click Save Changes.

By default, the Status tab for the Kudu service displays a dashboard containing a limited set of charts. For details on the terminology used in these charts, and instructions on how to query for time-series data, display chart details, and edit charts, see Charting Time-Series Data.

The Kudu service's Charts Library tab also displays a dashboard containing a much larger set of charts, organized by categories such as process charts, host charts, CPU charts, and so on, depending on the entity (service, role, or host) that you are viewing. You can use these charts to keep track of disk space usage, the rate at which data is being inserted/modified in Kudu across all tables, or any critical cluster events. You can also use them to keep track of individual tables. For example, to find out how much space a Kudu table is using on disk:

1. Go to the Kudu service and navigate to the Charts Library tab.
2. On the left-hand side menu, click Tables to display the list of tables currently stored in Kudu.
3. Click on a table name to view the default dashboard for that table. The Total Tablet Size On Disk Across Kudu Replicas chart displays the total size of the table on disk using a time-series chart.

   Hovering with your mouse over the line on the chart opens a small pop-up window that displays information about that data point. Click the data stream within the chart to display a larger pop-up window that includes additional information for the table at the point in time where the mouse was clicked.
