> I am conducting research on log related bugs. I tried to make a tool to fix repetitive
yet simple patterns of bugs that are related to logs. AccessControlExceptions occurred 114
times in Hadoop 2.7 source code and in 97% of the time they include a log statement. However
in later releases, these new files include AccessControlExceptions exceptions without any
log statements:

> /hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSDirStatAndListingOp.java
