format_command

ApiBulkCommandList format_command(cluster_name, service_name, body=body)

Format HDFS NameNodes.

Format HDFS NameNodes.

Submit a format request to a list of NameNodes on a service. Note that trying to format a previously formatted NameNode will fail.

Note about high availability: when two NameNodes are working in an HA pair, only one of them should be formatted.

Bulk command operations are not atomic, and may contain partial failures. The returned list will contain references to all successful commands, and a list of error messages identifying the roles on which the command failed.

hdfs_bootstrap_stand_by_command

ApiBulkCommandList hdfs_bootstrap_stand_by_command(cluster_name, service_name, body=body)

Bootstrap HDFS stand-by NameNodes.

Bootstrap HDFS stand-by NameNodes.

Submit a request to synchronize HDFS NameNodes with their assigned HA partners. The command requires that the target NameNodes are part of existing HA pairs, which can be accomplished by setting the nameservice configuration parameter in the NameNode's configuration.

The HA partner must already be formatted and running for this command to run.
