💡 Hint

Common Mistakes

Using 'data' or 'ingest' instead of 'master' for master node role.

Leaving the roles list empty.

Setting node.roles to ["master"] makes the node a master-eligible node.

💡 Hint

Common Mistakes

Confusing data nodes with master nodes.

Using 'ingest' role instead of 'data' for data nodes.

Setting node.roles to ["data"] configures the node to store and manage data.

💡 Hint

Common Mistakes

Using 'data' or 'master' roles instead of 'ingest' for ingest nodes.

Misspelling the role name.

The ingest role enables a node to process ingest pipelines before indexing documents.

4fill in blank

hard

Fill both blanks to configure a node as both master and data node.

Elasticsearch

node.roles: ["[1]", "[2]"]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using roles like 'ingest' or 'coordinating' instead of 'master' or 'data'.

Putting roles in the wrong order (order does not matter but consistency helps).

Combining master and data roles allows the node to manage cluster state and store data.

5fill in blank

hard

Fill all three blanks to configure a node with master, data, and ingest roles.

Elasticsearch

node.roles: ["[1]", "[2]", "[3]"]

Drag options to blanks, or click blank then click option'

Amaster

Bdata

Cingest

Dcoordinating

Attempts:

💡 Hint

Common Mistakes

Including 'coordinating' which is not a valid role name in this context.

Missing one of the three roles.

Setting roles to master, data, and ingest enables the node to manage cluster state, store data, and process ingest pipelines.
