--------------------------------------
Summary: Remove deprecated properties from core-default.xml
Key: HADOOP-19763
URL: https://issues.apache.org/jira/browse/HADOOP-19763
Project: Hadoop Common
Issue Type: Bug
Components: conf
Reporter: Chris Nauroth
Assignee: Chris Nauroth
Recent trunk changes now produce more assertive warnings about use of
deprecated configuration properties. With some of these deprecated properties
included in core-default.xml, that means every process launched logs the
warnings. Remove them from core-default.xml to avoid these warnings. (Note that
this does not take the step of actually removing the code that uses the
deprecated properties. They'll continue to work. We just don't want warnings
logged by default if the user didn't specifically use these properties.)

hadoop fs -ls /

core-default.xml is deprecated. Instead, use fs.defaultFS
2025-12-26 23:17:33,307 INFO Configuration.deprecation: io.bytes.per.checksum
in core-default.xml is deprecated. Instead, use dfs.bytes-per-checksum
