Hi, I need to copy files to an HDFS from my laptop but I am getting this error. If I copy files inside the hadoop server all goes well. But outside the cluster/server I get this error. IT IS DRIVING ME CRAZY. I installed 3 different clusters and same error. I changed configuration but I cannot make it work. ./hadoop fs -copyFromLocal testasd.txt hdfs://server1:9000/testing.txt 2019-05-02 18:26:07,445 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 2019-05-02 18:27:09,547 INFO hdfs.DataStreamer: Exception in createBlockOutputStream blk_1073741864_1040 org.apache.hadoop.net.ConnectTimeoutException: 60000 millis timeout while waiting for channel to be ready for connect. ch : java.nio.channels.SocketChannel[connection-pending remote=/172.17.0.2:50010] at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:534) at org.apache.hadoop.hdfs.DataStreamer.createSocketForPipeline(DataStreamer.java:253) at org.apache.hadoop.hdfs.DataStreamer.createBlockOutputStream(DataStreamer.java:1725) at org.apache.hadoop.hdfs.DataStreamer.nextBlockOutputStream(DataStreamer.java:1679) at org.apache.hadoop.hdfs.DataStreamer.run(DataStreamer.java:716) 2019-05-02 18:27:09,555 WARN hdfs.DataStreamer: Abandoning BP-581371184-172.17.13.14-1437578119536:blk_1073741864_1040 2019-05-02 18:27:09,885 WARN hdfs.DataStreamer: Excluding datanode DatanodeInfoWithStorage[172.17.0.2:50010,DS-a38d90cd-97c9-499b-914f-c710b2f0574a,DISK] 2019-05-02 18:27:10,058 WARN hdfs.DataStreamer: DataStreamer Exception org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /testing.txt._COPYING_ could only be replicated to 0 nodes instead of minReplication (=1).
