Suresh Srinivas commented on HDFS-3689: --------------------------------------- I also like the idea of sparse files. But I do not think it is going to be any easier than supporting variable length blocks. I also think applications need changes to be aware of sparse files. > Add support for variable length block > ------------------------------------- > > Key: HDFS-3689 > URL: https://issues.apache.org/jira/browse/HDFS-3689 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode, hdfs-client, namenode > Affects Versions: 3.0.0 > Reporter: Suresh Srinivas > Assignee: Suresh Srinivas > Attachments: HDFS-3689.000.patch, HDFS-3689.001.patch > > > Currently HDFS supports fixed length blocks.
