Specify or create an Ozone bucket for Cloudera Data Warehouse Private Cloud logs

This topic describes how to specify an Ozone bucket to store Cloudera Data Warehouse (CDW) Private Cloud Hive and Impala logs.

You can either re-use the Ozone bucket that is automatically configured for storing Cloudera Machine Learning (CML) Private Cloud logs or create a new bucket to store CDW logs separately. The Ozone bucket used to store CML logs usually has a cdplogs- prefix.

Use one of the following two methods depending on whether you want to use the existing CML log bucket or create a new one for CDW:
  • To select an existing Ozone bucket, use the ozone sh bucket list command from the Ozone shell on your Private Cloud Base cluster. The following example shows how you can list buckets by the cdplogs- prefix:

    ozone sh bucket list 03://ozone1/s3v --prefix=cdplogs
    {
       "metadata" : { },
       "volumeName" : "s3v",
       "name" : "cdplogs-av-dwx-env-96c47aa9",
       "storageType" : "DISK",
       "versioning" : false,
       "creationTime" : "2020-08-01T18:29:08.686z",
       "modificationTime" : "2020-08-03T18:29:08.686z",
       "encryptionKeyName" : null,
       "sourceVolume" : null,
       "sourceBucket" : null
    }
  • To create a new bucket on Ozone, use the ozone sh bucket create command from the Ozone shell on your Private Cloud Base cluster. The following example shows how to create a new Ozone bucket named cdw-logs-bucket:

    ozone sh bucket create 03://ozone1/s3v/cdw-logs-bucket
