changeCloudHadoopNodeSpec

Available in VPC

Upgrade the node specifications of a Cloud Hadoop cluster.

Syntax

The changeCloudHadoopNodeSpec syntax is as follows:

./ncloud vhadoop changeCloudHadoopNodeSpec \
    --cloudHadoopInstanceNo <cloud-hadoop-instance-no> \
    --masterNodeProductCode <master-node-product-code> \
    --edgeNodeProductCode <edge-node-product-code> \
    --workerNodeProductCode <worker-node-product-code> \
    [--regionCode <KR|SGN|JPN>] \
    [--output <json|xml>]

Options

This section describes the options available when running changeCloudHadoopNodeSpec.

Required options

The following options are required for changeCloudHadoopNodeSpec.

Options	Type	Required	Description
`--cloudHadoopInstanceNo`	String	Required	Cluster instance number See getCloudHadoopInstanceList.
`--masterNodeProductCode`	String	Conditional	Master node server type code At least one of `masterNodeProductCode`, `edgeNodeProductCode`, or `workerNodeProductCode` must be entered. See getCloudHadoopProductList.
`--edgeNodeProductCode`	String	Conditional	Edge node server type code At least one of `masterNodeProductCode`, `edgeNodeProductCode`, or `workerNodeProductCode` must be entered. See getCloudHadoopProductList.
`--workerNodeProductCode`	String	Conditional	Worker node server type code At least one of `masterNodeProductCode`, `edgeNodeProductCode`, or `workerNodeProductCode` must be entered. See getCloudHadoopProductList.

Common options

For information about the options common to all vhadoop subcommands, see Cloud Hadoop (VPC) options.

Examples

If the request to upgrade the Cloud Hadoop node specifications is successful, the cluster's configuration information and upgrade status are returned.

Command

The command example is as follows:

./ncloud vhadoop changeCloudHadoopNodeSpec \
    --cloudHadoopInstanceNo 34567890 \
    --edgeNodeProductCode SVR.VCHDP.EDGND.HICPU.C008.M016.NET.HDD.B050.G002 \
