-----------------------------
Summary: Redundant clone() in Configuration ctor
Key: FLINK-8075
URL: https://issues.apache.org/jira/browse/FLINK-8075
Project: Flink
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
In
flink-filesystems/flink-s3-fs-presto/src/main/java/org/apache/hadoop/conf/Configuration.java
, at line 703:
{code}
public Configuration(Configuration other) {
this.resources = (ArrayList<Resource>) other.resources.clone();
synchronized(other) {
if (other.properties != null) {
this.properties = (Properties)other.properties.clone();
}
{code}
The first clone() call is without synchronization and without null check.
