Uma Maheswara Rao G commented on HDFS-15117:
--------------------------------------------
[~ayushtkn], Thanks for checking.
I think we can't merge this patch to 3.2 because of protoBuff version
compatibility issues?
{code:java}
@Override
public GetECTopologyResultForPoliciesResponseProto
getECTopologyResultForPolicies(
RpcController controller, GetECTopologyResultForPoliciesRequestProto
req)
throws ServiceException {
try {
ProtocolStringList policies = req.getPoliciesList(); {code}
Looks like we used ProtocolStringList class which seems to be added in proto
2.6.
Since 3.2 was pointing to 2.5, this can't be compiled there.
