Hi team,
I'm working to run HDFS in kubernetes; all configuration is ready: kube-dns, hdfs-site.xml and ssh. But when I create files in HDFS I got the following exception. In exception, "10.0.1.126:50010" is the host's ip & port instead of container; is there any configuration to ask DFSClient to use container's IP instead of host IP? 16/06/04 14:06:23 INFO hdfs.DFSClient: Exception in createBlockOutputStream java.net.ConnectException: Connection refused at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:744) at org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:206) at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:531) at org.apache.hadoop.hdfs.DFSOutputStream.createSocketForPipeline(DFSOutputStream.java:1537) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.createBlockOutputStream(DFSOutputStream.java:1313) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.nextBlockOutputStream(DFSOutputStream.java:1266) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:449) 16/06/04 14:06:23 INFO hdfs.DFSClient: Abandoning BP-223491250-172.1.78.2-1465048638628:blk_1073741825_1001 16/06/04 14:06:23 INFO hdfs.DFSClient: Excluding datanode DatanodeInfoWithStorage[10.0.1.126:50010,DS-a2c2d3db-790c-4b76-81f6-856c809b01e2,DISK] 16/06/04 14:06:23 WARN hdfs.DFSClient: DataStreamer Exception org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /user/root/QuasiMonteCarlo_1465049182505_2071986941/in/part0 could only be replicated to 0 nodes instead of minReplication (=1).
