> Running teragen failed in the version of hadoop-3.1, and hdfs server is 2.8.
> {code:java}
> bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-3.1.0-SNAPSHOT.jar teragen 100000 /teragen
> {code}
> The reason of failing is 2.8 HDFS does not have setErasureCodingPolicy.
> one solution is parsing RemoteException in JobResourceUploader#disableErasure like this:
> {code:java}
> private void disableErasureCodingForPath(FileSystem fs, Path path)
> throws IOException {
> try {
> if (jtFs instanceof DistributedFileSystem) {
> LOG.info("Disabling Erasure Coding for path: " + path);
> DistributedFileSystem dfs = (DistributedFileSystem) jtFs;
> dfs.setErasureCodingPolicy(path,
> SystemErasureCodingPolicies.getReplicationPolicy().getName());
> }
> } catch (RemoteException e) {
> if (!e.getClassName().equals(RpcNoSuchMethodException.class.getName())) {
> throw e;
> } else {
> LOG.warn(
> "hdfs server does not have method disableErasureCodingForPath,"
> + " and skip disableErasureCodingForPath", e);
> }
> }
> }
> {code}
> Does anyone have better solution?
