I tried to load json data from my local into hadoop hdfs, I use these commands, and it throwing exception:
hadoop fs -copyFromLocal path/files/file.json input/
hadoop fs -put path/files/file.json input/
I've check using jps
command, found out that hadoop is running.
26039 ResourceManager
30858 SecondaryNameNode
35605 Jps
26147 NodeManager
30714 DataNode
This is detail of the exception:
WARN hdfs.DFSClient: DataStreamer Exception org.apache.hadoop.ipc.RemoteException(java.io.IOException): File path/files/file.json._COPYING_ could only be replicated to 0 nodes instead of minReplication (=1). There are 0 datanode(s) running and no node(s) are excluded in this operation.

How should I do? I need the data to be loaded into hdfs. Thanks in advance.
This recently happened to me and it was because the HDFS utilization was close to 100%. You can check your usage by running:
hdfs dfs -df -h
Increasing the HDFS size by increasing the number of cluster nodes solved the problem.
