Parameter Description
cluster The name of the cluster on which to run the command.
credential (For cold tier only) The path to the credentials file to use to access the tier.
Note: You cannot modify the bucket name in the credentials file after the tier is created; only the accesskey and the secretkey can be modified.
For more information, see Setting up a Credentials File for Connecting to a Cold Tier Using the CLI or REST API.
credential_str (For cold tier only) The region, bucket, and credentials, access key and secret key, specified in JSON format. Either this or -credential is required to connect to a cold tier.
force Required to force a change of any of the following:
  • Bucket on the tier where data is offloaded.
  • Region where the bucket resides.
  • URL (or endpoint) of the tier.
Value can be one of the following:
  • true — to force a change
  • false — to not change
The default value is false.
name The name of the tier.
tag (For cold tier only) The tier to connect to. Value can be one of the following:
  • S3-GCS
  • S3-HDS
  • S3-IBM
  • S3-AWS
  • S3-Others
  • Azure-Blobs
The MAST Gateway uses this to determine the connector library (such as libcurl, etc.) to use.
Note: You must specify this parameter to connect to Azure.
url (For cold tier only) The URL (or endpoint) of the tier. This can be modified only with the -force option. See Specifying the Vendor/Object Store for a Cold Tier for information on the tier endpoints and supported authentication protocols.
Note: If the credentials for the new URL are different, specify the new credentials through the credentials file or using the credential_str parameter.


Modify the credentials (credential file) used to access the tier:

# /opt/mapr/bin/maprcli tier modify -name testCold -credential credentials.txt -json
	"timeofday":"2018-02-26 10:38:01.090 GMT-0800 AM",
		"Successfully updated tier: 'ksTestCold'"
# curl -k -X POST '' --user mapr:mapr

Modify the tier by passing the credentials as a string:

# maprcli tier modify -name testCold -credential_str '{"bucketName":"testbucket","credentials":{"accessKey":"ABCDEFGHIJKL","secretKey":"MNOPQRSTUVWXYZ"}}' -json
	"timeofday":"2018-05-16 08:31:22.668 GMT-0700 AM",
		"Successfully updated tier: 'testCold'"
# curl -k -X POST 'https://abc.sj.us:8443/rest/tier/modify?name=testCold&credential_str=%7B%22buck3A%22testbucket%22%2C%22credentials%22%3A%7B%22accessKey%22%3A%22ABCDEFGHIJKLMN%22%2C%22secretKey%22%3A%22OPQRSTUVWXYZ%22%7D%7D' --user mapr:mapr
