Hi folks.. I have some doubt while thinking of formatting of namenode.. Actually i am doing my project in Apache Giraph which makes use of hadoop environment to run the job..
While running various job,i noticed that /app/hadoop/tmp/dfs/name/data 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.. Thanks
