Julia Kinga Marton commented on OOZIE-3542:
-------------------------------------------
Thank you [~zsombor] for the fix.
I would have two small comments related this:
* Please rename the test class to TestECPolicyDisabler.java
* Please mark somewhere in the name of SystemErasureCodingPolicies that is
created for tested purposes, so when we are doing class search to know it even
without opening it. (for example I would rename it to
SystemErasureCodingPoliciesForTest)
> Handle better old Hdfs implementations in ECPolicyDisabler

>
> 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.
