# [DRILL-8525](https://issues.apache.org/jira/browse/DRILL-8525): migrate fully to Apache Commons Collections 4.x ## Description To my surprise, Drill still uses classes from commons-collections (`3.x` release) in a few places, and Drill has not even declared it as a dependency. Drill used transitive dependency from `hadoop-commons`: ``` [INFO] --- dependency:3.6.1:tree (default-cli) @ drill-java-exec --- [INFO] org.apache.drill.exec:drill-java-exec:jar:1.22.0-SNAPSHOT [INFO] +- org.apache.hadoop:hadoop-common:jar:3.3.6:compile [INFO] | \- commons-collections:commons-collections:jar:3.2.2:compile [INFO] \- org.apache.commons:commons-collections4:jar:4.4:compile ``` But starting from `3.4.2` release, Hadoop drops it: https://issues.apache.org/jira/browse/HADOOP-15760 Time to clean our code too and completely migrate to `4.x` :) ## Documentation No user-visible changes ## Testing Unit tests -- This is an automated message from the Apache Git Service.
