HDFS client doesn't work for remote hadoop

[inzheneher]

Hi, guys.
I've got the issue:

1. I have k8s cluster up with hadoop on board.
2. hdfs client works fine inside cluster if I try to put files from namenode to datanode via hdfs dfs -put /path/to/local/file /path/to/somewhere
3. When I try to do the same things from local PC with hdfs client and port-forward kubectl port-forward svc/my-hdfs-namenode 50070:50070 I've got an exception:
   hadoop fs -ls / 2019-09-05 16:58:07,514 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 2019-09-05 16:58:08,270 WARN net.NetUtils: Unable to wrap exception of type class org.apache.hadoop.ipc.RpcException: it has no (String) constructor java.lang.NoSuchMethodException: org.apache.hadoop.ipc.RpcException.<init>(java.lang.String) at java.lang.Class.getConstructor0(Class.java:3082) at java.lang.Class.getConstructor(Class.java:1825) at org.apache.hadoop.net.NetUtils.wrapWithMessage(NetUtils.java:830) at org.apache.hadoop.net.NetUtils.wrapException(NetUtils.java:806) at org.apache.hadoop.ipc.Client.getRpcResponse(Client.java:1515) at org.apache.hadoop.ipc.Client.call(Client.java:1457) at org.apache.hadoop.ipc.Client.call(Client.java:1367) at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:228) at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:116) at com.sun.proxy.$Proxy9.getFileInfo(Unknown Source) at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.getFileInfo(ClientNamenodeProtocolTranslatorPB.java:900) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:422) at org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invokeMethod(RetryInvocationHandler.java:165) at org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invoke(RetryInvocationHandler.java:157) at org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invokeOnce(RetryInvocationHandler.java:95) at org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:359) at com.sun.proxy.$Proxy10.getFileInfo(Unknown Source) at org.apache.hadoop.hdfs.DFSClient.getFileInfo(DFSClient.java:1660) at org.apache.hadoop.hdfs.DistributedFileSystem$29.doCall(DistributedFileSystem.java:1583) at org.apache.hadoop.hdfs.DistributedFileSystem$29.doCall(DistributedFileSystem.java:1580) at org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81) at org.apache.hadoop.hdfs.DistributedFileSystem.getFileStatus(DistributedFileSystem.java:1595) at org.apache.hadoop.fs.Globber.getFileStatus(Globber.java:65) at org.apache.hadoop.fs.Globber.doGlob(Globber.java:294) at org.apache.hadoop.fs.Globber.glob(Globber.java:149) at org.apache.hadoop.fs.FileSystem.globStatus(FileSystem.java:2016) at org.apache.hadoop.fs.shell.PathData.expandAsGlob(PathData.java:326) at org.apache.hadoop.fs.shell.Command.expandArgument(Command.java:249) at org.apache.hadoop.fs.shell.Command.expandArguments(Command.java:232) at org.apache.hadoop.fs.shell.FsCommand.processRawArguments(FsCommand.java:104) at org.apache.hadoop.fs.shell.Command.run(Command.java:176) at org.apache.hadoop.fs.FsShell.run(FsShell.java:328) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:76) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:90) at org.apache.hadoop.fs.FsShell.main(FsShell.java:391) ls: Failed on local exception: org.apache.hadoop.ipc.RpcException: RPC response exceeds maximum data length; Host Details : local host is: "laptop/127.0.1.1"; destination host is: "localhost":50070;

My core-site.xml:
<configuration> <property> <name>fs.defaultFS</name> <value>hdfs://127.0.0.1:50070</value> </property> </configuration>

My hdfs-site.xml:
<configuration> </configuration>

So, what am I doing wrong?
