> [ERROR] /home/chia7712/oozie/tools/src/test/java/org/apache/oozie/tools/TestECPolicyDisabler.java:[50,71] getErasureCodingPolicy(org.apache.hadoop.fs.Path) in org.apache.oozie.tools.TestECPolicyDisabler.MockDistributedFileSystem cannot override getErasureCodingPolicy(org.apache.hadoop.fs.Path) in org.apache.hadoop.hdfs.DistributedFileSystem
> return type org.apache.hadoop.hdfs.protocol.SystemErasureCodingPolicies.ReplicationPolicy is not compatible with org.apache.hadoop.hdfs.protocol.ErasureCodingPolicy
> {quote}
> The root cause is the method `getErasureCodingPolicy` was introduced in hadoop 3 and the method signature is different to mock fs of TestECPolicyDisabler. Fortunately, all we want to test is the static method 'ECPolicyDisabler#check' so we can add a new argument to make it be able to check another method.
