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..
That's right you will lose all the HDFS data, therefore you need take backup of your critical data from HDFS to some other place. If you are using Logical volumes then it would better to add more space on the particular volume/mount point.
