-----------------------------------
Summary: Concurrency issues when using Configuration iterator
Key: HADOOP-13500
URL: https://issues.apache.org/jira/browse/HADOOP-13500
Project: Hadoop Common
Issue Type: Bug
Components: conf
Reporter: Jason Lowe
It is possible to encounter a ConcurrentModificationException while trying to
iterate a Configuration object. The iterator method tries to walk the
underlying Property object without proper synchronization, so another thread
simultaneously calling the set method can trigger it.
