Review request for oozie.
Bugs: OOZIE-3542
https://issues.apache.org/jira/browse/OOZIE-3542
Repository: oozie-git
Description
-------
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.
