dfsio does not work if mapreduce.output.fileoutputformat.compress is true

[kyungwan-nam]

What happened:

dfsio was failed as below.

dfsio assumes the output file is part-00000.
but, it would be part-00000.gz if mapreduce.output.fileoutputformat.compress is true in the mapred-site.xml

Anything else we need to know?

Environment:

• JuiceFS version (use juicefs --version) or Hadoop Java SDK version:
• Cloud provider or hardware configuration running JuiceFS:
• OS (e.g cat /etc/os-release):
• Kernel (e.g. uname -a):
• Object storage (cloud provider and region, or self maintained):
• Metadata engine info (version, cloud provider managed or self maintained):
• Network connectivity (JuiceFS to metadata engine, JuiceFS to object storage):
• Others:
