In a research project, we analyzed the source code of Hadoop looking for comments with on-hold SATDs (self-admitted technical debt) that could be fixed already. An on-hold SATD is a TODO/FIXME comment blocked by an issue. If this blocking issue is already resolved, the related todo can be implemented (or sometimes it is already implemented, but the comment is left in the code causing confusions). As we found a few instances of these in Hadoop, we decided to collect them in a ticket, so they are documented and can be addressed sooner or later.
A list of code comments that mention already closed issues.
- A code comment suggests making the setJobConf method deprecated along with a mapred package
HADOOP-1230. HADOOP-1230has been closed a long time ago, but the method is still not annotated as deprecated.
- A comment mentions that the return type of the getDefaultFileSystem method should be changed to AFS when
Indeed, this change was done in the related commit of
Thus, the comment could be removed.
