> DFS Used space is not correct computed on frequent append operations
> --------------------------------------------------------------------
>
> Key: HDFS-6489
> URL: https://issues.apache.org/jira/browse/HDFS-6489
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.2.0, 2.7.1, 2.7.2
> Reporter: stanley shi
> Assignee: Weiwei Yang
> Attachments: HDFS-6489.001.patch, HDFS-6489.002.patch, HDFS6489.java
>
>
> The current implementation of the Datanode will increase the DFS used space
> on each block write operation. This is correct in most scenario (create new
> file), but sometimes it will behave in-correct(append small data to a large
> block).
> For example, I have a file with only one block(say, 60M). Then I try to
> append to it very frequently but each time I append only 10 bytes;
> Then on each append, dfs used will be increased with the length of the
> block(60M), not teh actual data length(10bytes).
> Consider in a scenario I use many clients to append concurrently to a large
> number of files (1000+), assume the block size is 32M (half of the default
> value), then the dfs used will be increased 1000*32M = 32G on each append to
> the files; but actually I only write 10K bytes; this will cause the datanode
> to report in-sufficient disk space on data write.
