Abstract

A method, system, and apparatus for sending a request for data to a worldwide name node; wherein the worldwide name node is communicatively coupled to worldwide data nodes, sending from the worldwide name node to the worldwide data nodes the request for data; wherein each of the worldwide data nodes serves as an index for a cluster of data, processing at each of the worldwide data nodes the request for information; and returning the result to the world wide name node.

Claims

1. A computer implemented method for accessing worldwide comprising:

sending a request for data to a worldwide name node;

wherein the worldwide name node is communicatively coupled to worldwide data nodes;

wherein a worldwide data hierarchy is layered over the worldwide name node and worldwide data nodes;

wherein the worldwide data hierarchy classifies data distributed across the worldwide data nodes into categories according to the type of data stored on the worldwide data nodes;

wherein the classification of the data into categories of the worldwide hierarchy is enabled to be unrelated to the underlying location of the data;

wherein the worldwide data hierarchy further maps the data categorization to the location of the worldwide data nodes; and

wherein worldwide data structure enable analysis of data distributed across the worldwide data nodes regardless of the location of the underlying data based on a requested to analyze a type of categorized data;

sending from the worldwide name node to the worldwide data nodes the request for data according to the worldwide hierarchy;

wherein each of the worldwide data nodes serves as an index for a cluster of data;

processing at each of the worldwide data nodes the request for data according to the worldwide hierarchy; and

returning the result to the world wide name node.

2. The method of claim 1 wherein the data request is to determine what namespaces are available for a given data grouping;

wherein a namespace is an information categorization for the given grouping of data.

3. The method of claim 1 wherein the data request is to provide the specific data located within a given namespace for the request.

4. The method of claim 2 wherein the worldwide data node is collocated on a name node and provides data location services;

wherein the data location services are enabled to provide the location of data for a request.

5. The method of claim 1 wherein at least two of the data nodes are in geographically disperse locations.

6. The method of claim 2 wherein the physical location of the data is abstracted from the result of the request.

7. The method of claim 4 wherein the worldwide data node enables accessing, reading, executing algorithm and data jobs on the data.

8. A computer program product comprising:

a non-transitory computer readable medium encoded with computer executable program code, the code configured to enable one or more processors to execute;

sending a request for data to a worldwide name node;

wherein the worldwide name node is communicatively coupled to worldwide data nodes;

wherein a worldwide data hierarchy is layered over the worldwide name node and worldwide data nodes;

wherein the worldwide data hierarchy classifies data distributed across the worldwide data nodes into categories according to the type of data stored on the worldwide data nodes;

wherein the classification of the data into categories of the worldwide hierarchy is enabled to be unrelated to the underlying location of the data;

wherein the worldwide data hierarchy further maps the data categorization to the location of the worldwide data nodes; and

wherein worldwide data structure enable analysis of data distributed across the worldwide data nodes regardless of the location of the underlying data based on a requested to analyze a type of categorized data;

sending from the worldwide name node to the worldwide data nodes the request for data according to the worldwide hierarchy;

wherein each of the worldwide data nodes serves as an index for a cluster of data;

processing at each of the worldwide data nodes the request for data according to the worldwide hierarchy; and

returning the result to the world wide name node.

9. The computer program product of claim 8 wherein the data request is to determine what namespaces are available for a given data grouping;

wherein a namespace is an information categorization for the given grouping of data.

10. The computer program product of claim 8 wherein the data request is to provide the specific data located within a given namespace for the request.

11. The computer program product of claim 9 wherein the worldwide data node is collocated on a name node and provides data location services;

wherein the data location services are enabled to provide the location of data for a request.

12. The computer program product of claim 8 wherein at least two of the data nodes are in geographically disperse locations.

13. The computer program product of claim 8 wherein the physical location of the data is abstracted from the result of the request.

14. The computer program product of claim 8 wherein the worldwide data node enables accessing, reading, executing algorithm and data jobs on the data.

15. An apparatus comprising:

one or more processors; and

a send module, configurable to operate on one or more of the one or more processors, configured to send a request for data to a worldwide name node;

wherein the worldwide name node is communicatively coupled to worldwide data nodes;

wherein a worldwide data hierarchy is layered over the worldwide name node and worldwide data nodes;

wherein the worldwide data hierarchy classifies data distributed across the worldwide data nodes into categories according to the type of data stored on the worldwide data nodes;

wherein the classification of the data into categories of the worldwide hierarchy is enabled to be unrelated to the underlying location of the data;

wherein the worldwide data hierarchy further maps the data categorization to the location of the worldwide data nodes; and

wherein worldwide data structure enable analysis of data distributed across the worldwide data nodes regardless of the location of the underlying data based on a requested to analyze a type of categorized data;

a sender module, configurable to operate on one or more of the one or more processors, configured to send from the worldwide name node to the worldwide data nodes the request for data;

wherein each of the worldwide data nodes serves as an index for a cluster of data according to the worldwide hierarchy;

a processing module, configurable to operate on one or more of the one or more processors, configured to process at each of the worldwide data nodes the request for data according to the worldwide hierarchy; and

a returning module configured to return the result to the world wide name node.

16. The apparatus of claim 15 wherein the data request is to determine what namespaces are available for a given data grouping;

wherein a namespace is an information categorization for the given grouping of data.

17. The apparatus of claim 15 wherein the data request is to provide the specific data located within a given namespace for the request.

18. The apparatus of claim 16 wherein the worldwide data node is collocated on a name node and provides data location services;

wherein the data location services are enabled to provide the location of data for a request.

19. The apparatus of claim 15 wherein at least two of the data nodes are in geographically disperse locations.

20. The apparatus of claim 16 wherein the physical location of the data is abstracted from the result of the request.
