Not able to read or write to Hortonworks sandbox HDP 2.5

Hello Team,

 

I'm trying to write and read data to HDP 2.5 using talend, but I'm getting error in both cases

 

While writing 

 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. 

 

 While reading

 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

 

Though the NameNodes seem to be working fine
