i gone through the logs and i come to know that this is purely HDFS issue not flume,   so i fix it as follows:   step1:   stop all the services   Step2:   started name node   then when am trying to start the data nodes on the 3 servers,one of the server throwig the error message  /var/log/  ----No such file/directory /var/run --No such file/directory   But these files are existing so i check the permissions on those two differ from second server to third server   So given the permission to those directories to  be in sink   and then started all the services then flume working fine,   thats it.     -Thankyou ...
