Hi, thanks so much for the information. But for now I deleted the hdfs /tmp folder contents which were lying there for a long time. This freed up about 500GB of space on hdfs in total, and that particular disk went down to 82% from 90%. How is it possible? The other disk also which had the same issue went down to 82%. My question is: did the disk usage go down just because of deleting the /tmp folder or does the disk size fluctuate because of some other running jobs too?? Also, I thought mapreduce utilizes local disk for storing intermediate data, so what is actually stored in hdfs tmp directory? I assumed this is where the intermediate data is stored, which is utilizing hdfs space. Thanks again in advance.
