I'm trying to write and read data to HDP 2.5 using talend, but I'm getting error in both cases
org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /user/maria_dev/Talend_test_file.txt
could only be replicated to 0 nodes instead of minReplication (=1). There are 1 datanode(s) running and 1 node(s) are excluded in this operation.
Exception in component tHDFSInput_1 (ReadHDFS)
org.apache.hadoop.hdfs.BlockMissingException: Could not obtain block: BP-1464254149-172.17.0.2-1477381671113:blk_1073743380_2607 file=/user/maria_dev/Student.csv
