Usage

To create a warm tier:
maprcli tier create
          [ -cluster <cluster_name> ]
          -name <tier_name>
          -type ectier
          [ -dbtopology <path> ]
To create a cold tier:
maprcli tier create 
          [ -cluster <cluster_name> ]
          -name <tier_name> 
          -type cold -url <tier_URL> 
          -credential|credential_str <credential> 
          [ -dbtopology <path> ] 
          [ -tag S3-AWS|S3-GCS|S3-HDS|S3-IBM|Azure-Blobs|S3-Others ]
Note: The -tag parameter is required for Azure.

Parameters

Parameter Description
cluster The name of the cluster on which to run the command.
credential (For tier of type cold only) The path to the credentials file to use for accessing the tier. The credentials file must already exist on the node from where the tier is being created. For more information, see Setting up a Credentials File for Connecting to a Cold Tier Using the CLI or REST API.
Note: Either this or -credential_str is required for creating a cold tier.
credential_str (For tier of type cold only) The credentials, access key and secret key, bucket name, and region in JSON format. Either this or -credential is required for creating a cold tier.
dbtopology The rack path to the volume where metadata is stored in DB tables. The default value is /data.
name The name of the tier.
tag (For tier of type cold only) The object store to connect to. Value can be one of the following:
  • S3-GCS (for Google Cloud Platform)
  • S3-HDS (for Hitachi HCP)
  • S3-IBM (for IBM Cloudsafe)
  • S3-AWS (for Amazon AWS)
  • Azure-Blobs (for Microsoft Azure)
  • S3-Others (for other all vendors)
The MAST Gateway uses this to determine the connector library (such as libcurl, etc.) to use. See Specifying the Vendor/Object Store for a Cold Tier for more information on the object store.
Note: This parameter is required for Azure.
type The type of tier to create. Value can be:
  • cold — to offload to low-cost storage alternative on the cloud
  • ectier — to offload to low-cost storage alternative on the MapR cluster
url (For tier of type cold only) The URL (or endpoint) of the tier in the following format: <protocol>://<IP|hostname>.<domain>. Fore more information, see Specifying the Vendor/Object Store for a Cold Tier. When specifying the URL (for S3), use double quotes.

If the protocol is https, the MAST Gateway uses HTTPS to upload data to the cold-tier. If the cold-tier storage does not support HTTPS, all tier related operations will fail. If the cold tier does not support HTTPS, set the protocol to http, which is the default.

Examples

Create a cold tier for offloading to S3:

# /opt/mapr/bin/maprcli tier create -name ksTestCold -type cold -url "s3.amazonaws.com" -credential credentials.txt -json
{
	"timestamp":1519669953410,
	"timeofday":"2018-02-26 10:32:33.410 GMT-0800 AM",
	"status":"OK",
	"total":0,
	"data":[
		
	],
	"messages":[
		"Successfully created tier: 'ksTestCold'"
	]
}
# curl -k -X POST 'https://abc.sj.us:8443/rest/tier/create?name=ksTestCold&type=cold&url=s3.amazonaws.com&credential=/root/credentials.txt' --user mapr:mapr
{"timestamp":1519679457859,"timeofday":"2018-02-26 01:10:57.859 GMT-0800 PM","status":"OK","total":0,"data":[],"messages":["Successfully created tier: 'ksTestCold'"]}

Create a EC tier for offloading to a erasure coded volume on the MapR cluster:

# /opt/mapr/bin/maprcli tier create -name ksTestEC -type ectier -json
{
	"timestamp":1519664750448,
	"timeofday":"2018-02-26 09:05:50.448 GMT-0800 AM",
	"status":"OK",
	"total":0,
	"data":[
		
	],
	"messages":[
		"Successfully created tier: 'ksTestEC'"
	]
}
# curl -k -X POST 'https://abc.sj.us:8443/rest/tier/create?name=ksTestEC&type=ectier' --user mapr:mapr
{"timestamp":1519679884411,"timeofday":"2018-02-26 01:18:04.411 GMT-0800 PM","status":"OK","total":0,"data":[],"messages":["Successfully created tier: 'ksTestEC'"]}

Create a cold tier by sending the credentials as a string:

# maprcli tier create -name testCold -type cold -url "s3.amazon.com" -credential_str '{"bucketName":"testbucket","credentials":{"accessKey":"ABCDEFGHIJKLM","secretKey":"OPQRSTUVWXYZ"}}' -json
{
	"timestamp":1526406945863,
	"timeofday":"2018-05-15 10:55:45.863 GMT-0700 AM",
	"status":"OK",
	"total":0,
	"data":[
		
	],
	"messages":[
		"Successfully created tier: 'testCold'"
	]
}
# curl -k -X POST 'https://abc.sj.us:8443/rest/tier/create?name=testCold&type=cold&url=s3.amazon.com&credential_str=%7B%22bucketName%22%3A%22testbucket%22%2C%22credentials%22%3A%7B%22accessKey%22%3A%ABCDEFGHIJKL%22%2C%22secretKey%22%3A%22OPQRSTUVWXYZ%22%7D%7D' --user mapr:mapr
{"timestamp":1526483636503,"timeofday":"2018-05-16 08:13:56.503 GMT-0700 AM","status":"OK","total":0,"data":[],"messages":["Successfully created tier: 'testCold'"]}
