@Vasilis Vagias That, but VirtualBox is smart enough to import even a VMWare image. My opinion is that you downloaded an incomplete file due to your Chrome Download Manager, not capable to resume download in case of temporary connectivity issues. What is the size of your file? It should be around 9.5 GB. Try to use a download manager that is capable to resume download and do a size check at the end. Try folx, that if you are on mac. ... View more

@Sami Ahmad The output you posted shows that 3.6 GB is used and available space is 150.8 GB. You are concerned that available should show 240.5 GB - 3.6 GB = 236.9 GB and not 150.8 GB. Here is how it goes. HDFS has blocks and each block has a size, let's assume 128 MB/block.If you have multiple small files they will underuse the block size. For example, if you have 10 files of 64 MB each stored in 10 blocks of 128 MB they will underuse the blocks at 50%. The remaining space in those blocks CANNOT be used by other files. It is just wasted and it is not reported as AVAILABLE. The way hdfs dfs -df -h command works for AVAILABLE is this: it determines the number of blocks available for storing new data (empty) and multiplies that with the block size. Just looking at your numbers above, it shows that the wasted space is 236.9-150.8=86.1 GB. That shows that your block size is set to a value higher than your average file size, about 50%. This is not uncommon, but be aware. I hope this explanation is good enough. Please don't forget to vote/accept answer that answered your question. ... View more
