Enhanced authentication method for Hadoop job containers

1. A method of providing content authentication of job containers in a Hadoop Distributed File System (HDFS) network cluster having a name node and a data node, comprising:

inputting job specific files and encryption elements into a first file signing engine component executed on the name node to generate a first identity value for the content;

inputting the job specific files and the encryption elements into a second file signing engine component executed on the data node to generate a second identity value for the content;

comparing the first identity value with the second identity value; and

proceeding with a task processing the content if the comparing yields a match or aborting the task if the comparing does not yield a match,

wherein the encryption elements comprise a unique key and an initial value, and the unique key comprises a value indicating an identity of a job owner issuing the task, and further wherein the initial value comprises a unique session key that is randomly generated for the task.

2. The method of claim 1 further comprising, for each of the first and second file signing engine components, inputting the job specific files and the unique key into a digestion function to generate digested code, wherein the digestion function comprises a cryptographic hash function.

3. The method of claim 2 further comprising, for each of the first and second file signing engine components, inputting the digested code and the initial value into a combining function to generate a respective identity value of the first and second identity values.

4. The method of claim 3 wherein each of the unique key, initial value, and digested code are of a bit length, k.

5. The method of claim 1 wherein the data node comprises a plurality of data nodes, and wherein the job containers are spread across the plurality of data nodes for execution of the task processing the content.

6. A system of providing content authentication of job containers in a Hadoop Distributed File System (HDFS) network cluster having a name node and a data node, comprising:

a first file signing engine component executed on the name node receiving job specific files and encryption elements to generate a first identity value for the content;

a second file signing engine component executed on the data node receiving job specific files and encryption elements to generate a second identity value for the content;

a comparator comparing the first identity value with the second identity value; and

an execution component proceeding with a task processing the content if the comparing yields a match or aborting the task if the comparing does not yield a match,

wherein the encryption elements comprise a unique key and an initial value, and the unique key comprises a value indicating an identity of a job owner issuing the task, and further wherein the initial value comprises a unique session key that is randomly generated for the task.

7. The system of claim 6 wherein the first file signing engine comprises:

a first digestion function receiving the unique key and the job specific files to generate first digested code;

a first combining function receiving the initial value and the first digested code to generate the first identity value for the name node.

8. The system of claim 7 wherein the second file signing engine comprises:

a second digestion function receiving the unique key and the job specific files to generate second digested code;

a second combining function receiving the initial value and the second digested code to generate the second identity value for the data node.

9. The system of claim 8 wherein each of the first and second digestion functions comprises a cryptographic hash function.

10. The system of claim 9 wherein each of the unique key, initial value, and first and second digested codes are of a bit length, k.

11. The system of claim 10 wherein the data node comprises a plurality of data nodes, and wherein the job containers are spread across the plurality of data nodes for execution of the task processing the content.

12. A computer program product, comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein, the computer-readable program code adapted to be executed by one or more processors to perform a method of providing content authentication of job containers in a Hadoop Distributed File System (HDFS) network cluster having a name node and a data node, the method comprising:

inputting job specific files and encryption elements into a first file signing engine component executed on the name node to generate a first identity value for the content;

inputting the job specific files and the encryption elements into a second file signing engine component executed on the data node to generate a second identity value for the content;

comparing the first identity value with the second identity value; and

proceeding with a task processing the content if the comparing yields a match or aborting the task if the comparing does not yield a match,

wherein the encryption elements comprise a unique key and an initial value, and the unique key comprising a value indicating an identity of a job owner issuing the task, and further wherein the initial value comprising a unique session key that is randomly generated for the task.

13. The computer program product of claim 12 further comprising, for each of the first and second file signing engine components:

inputting the job specific files and the unique key into a digestion function to generate digested code, wherein the digestion function comprises a cryptographic hash function, and

inputting the digested code and the initial value into a combining function to generate a respective identity value of the first and second identity values.
