Ivan A. Veselovsky created HADOOP-8993:
------------------------------------------
Summary: Remove unused methods from FileUtil class
Key: HADOOP-8993
URL: https://issues.apache.org/jira/browse/HADOOP-8993
Project: Hadoop Common
Issue Type: Improvement
Reporter: Ivan A. Veselovsky
Priority: Minor
Some methods in class org.apache.hadoop.fs.FileUtil are used neither in project
code nor in tests, that is, are a dead code.
This lowers the overall coverage of that class.
The suggested patches remove the unused methods.
Note: one of #copy(5) method is unused in 0.23 branch, while is used in
branch-2, so the patches for these branches are different.
