Translation-based name node configuration for object access in a multi-tier storage system

A method comprising:

• providing a multi-tier storage system comprising a front-end storage tier, a back-end storage tier and a data mover module coupled to the front-end and back-end storage tiers to control movement of data between the storage tiers;
• providing a translator associated with the multi-tier storage system, the translator implementing a plurality of translation services and one or more index tables;
• determining, in conjunction with a given one of the translation services that accesses at least one of the one or more index tables, a dynamically loadable namespace identifier associated with an application running on an analysis node that communicates with the multi-tier storage system over at least one network;
• and
• configuring a name node corresponding to the dynamically loadable namespace identifier;
• wherein the dynamically loadable namespace identifier identifying a dynamically loadable namespace that comprises at least a root element and a plurality of directories;
• wherein particular objects of an object store of the back-end storage tier are made accessible to the application via the name node;
• wherein the name node is configured at least in part utilizing an index table that stores a plurality of dynamically loadable namespace identifiers, for respective different application types, in association with respective corresponding object identifiers of respective dynamically loadable namespace objects stored in the object store of the back-end storage tier, the dynamically loadable namespace objects identifying respective different sets of objects of the object store that are accessible to respective applications of the respective different application types;
• wherein a given entry of the index table for one of the dynamically loadable namespace identifiers comprises its associated object identifier and a location flag indicating if the corresponding name node is currently implemented in one or more of the front-end storage tier, the back-end storage tier and the translator;
• and
• wherein the providing, determining and configuring are implemented using at least one processing device comprising a processor coupled to a memory.

A non-transitory processor-readable storage medium having stored therein program code of one or more software programs, for use in conjunction with a multi-tier storage system comprising a front-end storage tier, a back-end storage tier and a data mover module coupled to the front-end and back-end storage tiers to control movement of data between the storage tiers, the multi-tier storage system being associated with a translator implementing a plurality of translation services and one or more index tables, wherein the program code when executed by at least one processing device causes said processing device:

• to determine, in conjunction with a given one of the translation services that accesses at least one of the one or more index tables, a dynamically loadable namespace identifier associated with an application running on an analysis node that communicates with the multi-tier storage system over at least one network;
• and
• to configure a name node corresponding to the dynamically loadable namespace identifier;
• the dynamically loadable namespace identifier identifying a dynamically loadable namespace that comprises at least a root element and a plurality of directories;
• wherein particular objects of an object store of the back-end storage tier are made accessible to the application via the name node;
• wherein the name node is configured at least in part utilizing an index table that stores a plurality of dynamically loadable namespace identifiers, for respective different application types, in association with respective corresponding object identifiers of respective dynamically loadable namespace objects stored in the object store of the back-end storage tier, the dynamically loadable namespace objects identifying respective different sets of objects of the object store that are accessible to respective applications of the respective different application types;
• and
• wherein a given entry of the index table for one of the dynamically loadable namespace identifiers comprises its associated object identifier and a location flag indicating if the corresponding name node is currently implemented in one or more of the front-end storage tier, the back-end storage tier and the translator.
