Anonymous — Sat, 16 Nov 2024 12:08:15 GMT

Hi
i am practicing talend big data. i have download hadoop demo version from cloudera and try to load the csv file data into the hdfs out put component. i am getting an error "File /tmp/digjag.csv 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." i can see new file created in hadoop base. however there are no rows in it.
please see the attached image. i am using Talend big data 5.2.0
Can anyone please help me?
regards
Praveen Lingam

Hi,
In order to troubleshoot your issue:
Coud you please make sure the datanode is up looking at this URL: http://SERVER:8020.
If it is, could you make sure you still have enough free disk space to write your data into your HDFS?
If it is not, look at your namenode and datanode log files.
