-------------------------------------------
Summary: Improve TestDFSIO to support different InputFormat
Key: MAPREDUCE-7525
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7525
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: mapreduce-client
Affects Versions: 3.3.3
Reporter: zhixingheyi-tian
Currently, the TestDFSIO benchmark hardcodes the InputFormat to
SequenceFileInputFormat.class in the runIOTest method. This limits flexibility
for users who want to test different InputFormat implementations' performance,
particularly CombineSequenceFileInputFormat which is essential for handling
small file scenarios efficiently.
