-------------------------------------
Summary: Handle better old Hdfs implementations in ECPolicyDisabler
Key: OOZIE-3542
URL: https://issues.apache.org/jira/browse/OOZIE-3542
Project: Oozie
Issue Type: Bug
Components: tools
Reporter: Zsombor Gegesy
Assignee: Zsombor Gegesy
Currently, ECPolicyDisabler checks if the local hdfs implementation has the
necessary methods to get and set erasure coding policy. However, if the
namenode implementation is old, it could throw a
org.apache.hadoop.ipc.RemoteException with
RpcErrorCodeProto.ERROR_NO_SUCH_METHOD value in it.
In this case, ECPolicyDisabler fails, and prevents the installation to succeed.
This case should be handled just like, when erasure coding is not supported.
