Options

--ambari-metrics-collector <string>

The host name for the metrics collector. The value must be a resolvable hostname, FQDN, IPv4 or IPv6 address.

--ambari-namenode <string>

A point of contact in the access zone that Hadoop services managed through the Ambari interface should connect through. The value must be a resolvable IPv4 address or a SmartConnect zone name.

--ambari-server <string>

The Ambari server that receives communication from an Ambari agent. The value must be a resolvable hostname, FQDN, IPv4 or IPv6 address.

--authentication-mode {simple_only | kerberos_only}

The authentication method used for HDFS connections through the specified access zone. The default value for authentication-mode is simple_only for OneFS 8.2.1 and later versions.

--data-transfer-cipher {none | aes_128_ctr | aes_192_ctr | aes_256_ctr}

The Advanced Encryption Standard (AES) cipher to use for wire encryption.

--default-block-size <size>

The block size (in bytes) reported by the HDFS service. K, M, and G; for example, 64M, 512K, 1G, are valid suffixes. The default value is 128 MB.

--default-checksum-type {none | crc32 | crc32c}

The checksum type reported by the HDFS service. The default value is none

--hadoop-version-3-or-later {true | false}

Set the Hadoop client version as true if using Hadoop version 3 or later.

--hdfs-acl-enabled {true | false}

Enables or disables the HDFS ACL.

--odp-version <string>

The version of the Open Data Platform (ODP) stack repository, including build number if one exists, installed by the Ambari server. This is required to support ODP upgrades on other systems that are part of the Hadoop cluster.

--root-directory <path>

Root path that contains HDFS data in the access zone that can be accessed by Hadoop compute client connections. The root directory must be within the access zone base directory.

--service {yes | no}

Enables or disables the HDFS service in the specified access zone. The HDFS service is enabled by default.

--verbose | -v

Display more detailed information.

--webhdfs-enabled {yes | no}

Enables or disables the WebHDFS in the specified access zone. WebHDFS is enabled by default.

--zone <string>

The access zone to which the HDFS settings apply.
