Fileset-based data locality enablement in distributed file systems

A computer program product, for fileset based data locality management in Distributed File Systems, the computer program product comprising:

• one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
• program instructions to, receive, by data locality manager, one or more fileset identifiers and associated one or more block allocation information, for storing in one or more data block locality tables;
• program instructions to, determine, by the data locality manager, one or more data block locality factors based on the one or more fileset identifiers and the one or more block allocation information, creating a collection of the one or more data block locality factors;
• program instructions to, store, by the data locality manager, the collection of the one or more data block locality factors in the one or more data block locality tables;
• program instructions to, receive, by the data locality manager, the one or more fileset identifiers for determining the collection of the one or more data block locality factors associated to the one or more fileset identifiers;
• and
• program instructions to, output, by the data locality manager, the collection of the one or more data block locality factors.

A computer system, for fileset based data locality management in Distributed File Systems, the computer system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
• program instructions to, receive, by data locality manager, one or more fileset identifiers and associated one or more block allocation information, for storing in one or more data block locality tables;
• program instructions to, determine, by the data locality manager, one or more data block locality factors based on the one or more fileset identifiers and the one or more block allocation information, creating a collection of the one or more data block locality factors;
• program instructions to, store, by the data locality manager, the collection of the one or more data block locality factors in the one or more data block locality tables;
• program instructions to, receive, by the data locality manager, the one or more fileset identifiers for determining the collection of the one or more data block locality factors associated to the one or more fileset identifiers;
• and
• program instructions to, output, by the data locality manager, the collection of the one or more data block locality factors.
