Hi,

As this mailing list has been migrated to us...@apex.apache.org. So please use us...@apex.apache.org  for further discussions or queries regarding usage of apache apex.

Regarding your query: 

Hadoop Location: must be location to hadoop binary (usually where you extract hadoop directory).  For eg: /usr/local/hadoop/bin/hadoop

DFS Location: must be hdfs root directory  format: /user/USERNAME/datatorrent for e.g: /user/deepak/datatorrent  

                         Also you may provide it through URI: hdfs://NAMENODE:PORT_NUM/user/USERNAME/datatorrent

Thanks,

Deepak

Thanks,

Deepak

 hdfs://namenode:9000/user/sid/datatorrent is this format correct ...can you please tell me its urgent

java.net.UnknownHostException: namenode

[Deepak Narkhede]

Hi,

NAMENODE is reference for hdfs namenode. If it is single node HDFS configured it must be localhost. Also refer to core-site.xml file to check your exact path to HDFS.

For e.g: 

deepak@deepak-HP-ProBook-650-G2:~$ cat /usr/local/hadoop/etc/hadoop/core-site.xml
