Re: HDFS Snapshots

Why would the state go backwards? Let me try to restate your scenario: t1: snapshot a file with length 5 t2: append to the file, now length 6 t3: delete the snapshot After this, since we deleted the snapshot, we only have the current filesystem state which is length 6. There's no "restore" funct

Re: HDFS Snapshots

Hi, Actually, how does namenode handle when block report is sent from datanodes? After removing snapshot the file size = 0.5*BLOCK_SIZE. but the block report says it is 0.6*BLOCK_SIZE,(if we do not shrink the block) there is a mismatch. On Tue, Oct 21, 2014 at 8:34 PM, Pushparaj Motamari wrote

Re: HDFS Snapshots

Hi, Generally the user expectation is to get back to the previous state of FileSystem, so we should see the old state of block(the block size should shrink). I couldn't find the semantics of this kind of operations in design document either. Thank You Pushparaj On Tue, Oct 21, 2014 at 8:23 PM,

Re: HDFS Snapshots

Hi Pushparaj, Based on those steps, isn't the expectation that you end up with a 0.6*size block at the end? Blocks are append only (i.e. only grow in length), so deleting a snapshot cannot result in a block shrinking. Best, Andrew On Tue, Oct 21, 2014 at 7:20 AM, Pushparaj Motamari wrote: > Hi

HDFS Snapshots

Hi, Consider the scenario below. /A/file.txt in HDFS 1. file.txt size = 0.5*(Size of Block). 2. Take Snapshot on directory A 3. Append to the file.txt, making its size as 0.6*(Size of Block) 4. Remove/delete the snapshot on folder taken in step2. My Question
