Thanks Claudio for your reply.. I think it is the problem due to less hard disk space. /app/hadoop/tmp/dfs/name/data this directory is almost full..
Should i format my namenode?? Will it create any problem?? I know if i format ,i will lose all my data residing in hdfs. Before formatting it,i will take backup of all the input files used to run giraph job.. Seeking your suggestions..
