Urgent Requirement: How to copy File from One cluster to another cluster using java client(throught java Program)
Hi All,
    Any one had gone through scenario to  copy file from one cluster to
another cluster using java application program (Using Hadoop FileSystem
API) .

  I have done some thing using java application but within the same cluster
it is working file while I am copying the file from one cluster to another
cluster I am getting the error.
