Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store. ## Pattern-based discovery and mapping requirements {#aws-emr-cluster__section_rpj_fj2_bgc} Verify the AWS discovery prerequisites : For more information, see the prerequisites section in [AWS discovery using patterns](https://www.servicenow.com/docs/Y0yjdHKR~_I76hi21l9C4A "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). Remove resources from the Resource Inclusion List table : Verify that the relevant resource isn't listed in the Resource Inclusion List \[sa_cloud_inventory_resource_whitelist\] table to avoid duplicate discovery. For more information on removing resources from the Resource Inclusion List, see [AWS Resource Inventory discovery with Patterns](https://www.servicenow.com/docs/eAqnoZkp8ZHs8uc6u0w1jQ "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). Enable the relevant pattern : The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see [Activate a disabled pattern](https://www.servicenow.com/docs/FMsw6rb9elo1cmkEw_pOug "If you want to use a pattern for discovery that's disabled by default, activate it manually.").{#aws-emr-cluster__activating-disabled-pattern-not-customization} Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables. ## Data stored in non-CMDB tables {#aws-emr-cluster__section_aq4_qkq_hfc} Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - EMR Cluster - Extended Inventory (LP) pattern. You can review the non-CMDB AWS tables by navigating to AllConfigurationAWS. You can also search the navigation filter for the specific pattern name. {#aws-emr-cluster__table_non_cmdb__entry__2} | Field | Description | |-|-| | Name \[name\] | Name of the EMR cluster. | | Object ID \[object_id\] | The Amazon Resource Name (ARN) of the EMR cluster. | | Cluster ID \[cluster_id\] | The unique identifier of the EMR cluster. | | State \[state\] | Current state of the EMR cluster. For example: RUNNING, WAITING, or TERMINATING. | | Configuration Item \[configuration_item\] | References the Cloud Resource \[cmdb_ci_cmp_resource\] table. | [Table 1. AWS EMR Cluster \[cmdb_aws_emr_cluster\]] {#aws-emr-cluster__table_non_cmdb} ## Data stored in CMDB tables {#aws-emr-cluster__section_ggp_ql2_bgc} Discovery and Service Mapping Patterns application populates data in the CMDB when running the Amazon AWS - EMR Cluster - Extended Inventory (LP) pattern. {#aws-emr-cluster__table_cmdb__entry__2} | Field | Description | |-|-| | Name \[name\] | Name of the EMR cluster. | | Object ID \[object_id\] | The ARN of the EMR cluster. | | Resource type \[resource_type\] | Type of resource. The value is set to AWS::EMR::Cluster. | | Install Status \[install_status\] | Install status of the resource. Default value is Installed. | | Operational status \[operational_status\] | Operational status of the resource. Default value is Operational. | [Table 2. Cloud Resource \[cmdb_ci_cmp_resource\]] {#aws-emr-cluster__table_cmdb} ## CI relationships {#aws-emr-cluster__section_dc4_ghc_dgc} The Amazon AWS - EMR Cluster - Extended Inventory (LP) pattern creates the following relationships and references to support Amazon EMR Cluster discovery. References link to records in other tables and don't appear in the CI Relationship \[cmdb_rel_ci\] table. {#aws-emr-cluster__table_relationships__entry__3} | CI | Relationship | CI | |-|-|-| | Cloud Resource \[cmdb_ci_cmp_resource\] | Hosted on::Hosts | AWS Datacenter \[cmdb_ci_aws_datacenter\] | [Table 3.
