Systems and methods for preventing input/output performance decrease after disk failure in a distributed file system
In accordance with embodiments of the present disclosure, a method may include receiving from a plurality of data nodes of a distributed file system an indication of whether a fault condition exists with respect to a storage resource of the respective data node. The method may also include receiving an input/output request for a storage resource of a particular data node from a host information handling system communicatively coupled to the distributed file system. The method may further include, responsive to the input/output request, directing the input/output request to the particular data node if no fault condition exists with respect to storage resources of the particular data node and directing the input/output request to another data node of the distributed file system if a fault condition exists with respect to one or more storage resources of the particular data node.
1. A method comprising:
receiving from a plurality of data nodes of a Hadoop distributed file system an indication of whether a fault condition exists with respect to a storage resource of the respective data node;
receiving an input/output request for a storage resource of a particular data node from a host information handling system communicatively coupled to the Hadoop distributed file system; and
responsive to the input/output request:
directing the input/output request to the particular data node if no fault condition exists with respect to storage resources of the particular data node; and
directing the input/output request to another data node of the Hadoop distributed file system if a fault condition exists with respect to one or more storage resources of the particular data node.
2. The method of claim 1 , wherein the input/output request comprises a read request.
3. The method of claim 1 , wherein the input/output request comprises a write request.
4. The method of claim 1 , wherein the fault condition comprises a disk failure associated with the storage resource.
5. An information handling system comprising:
a processor; and
a computer-readable medium having stored thereon a program of instructions configured to, when read and executed by the processor:
receive from a plurality of data nodes of a Hadoop distributed file system an indication of whether a fault condition exists with respect to a storage resource of the respective data node;
receive an input/output request for a storage resource of a particular data node from a host information handling system communicatively coupled to the Hadoop distributed file system; and
responsive to the input/output request:
direct the input/output request to the particular data node if no fault condition exists with respect to storage resources of the particular data node; and
direct the input/output request to another data node of the Hadoop distributed file system if a fault condition exists with respect to one or more storage resources of the particular data node.
6. The information handling system of claim 5 , wherein the input/output request comprises a read request.
7. The information handling system of claim 5 , wherein the input/output request comprises a write request.
8. The information handling system of claim 5 , wherein the fault condition comprises a disk failure associated with the storage resource.
9. An article of manufacture comprising:
a non-transitory computer readable medium; and
computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:
receive from a plurality of data nodes of a Hadoop distributed file system an indication of whether a fault condition exists with respect to a storage resource of the respective data node;
receive an input/output request for a storage resource of a particular data node from a host information handling system communicatively coupled to the Hadoop distributed file system; and
responsive to the input/output request:
direct the input/output request to the particular data node if no fault condition exists with respect to storage resources of the particular data node; and
direct the input/output request to another data node of the Hadoop distributed file system if a fault condition exists with respect to one or more storage resources of the particular data node.
10. The article of claim 9 , wherein the input/output request comprises a read request.
11. The article of claim 9 , wherein the input/output request comprises a write request.
12. The article of claim 9 , wherein the fault condition comprises a disk failure associated with the storage resource.
