Hi,
I need to get the information about Name Node and Data Node.I have only
information about ip and port of NameNode i.e.,
"hdfs://172.16.6.162:9000/file/data". With this information how to find the
Name Node and Data Node live or not?.
I also try to make a socket connection for given IP and port if is connection
Name Node is active but How to check Data Node is is active or not.
Because DataNode contains original data with out this we cannot write a data to
hdfs. And also port 9000 is changeable by user so that I want to ensure Hdfs is
running in given IP and port
Thanks & RegardsRamesh
