> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: runzhiwang
> Assignee: Yang Yu
> Priority: Major

> Datanode starts a background thread to process <TRUNCATING_blockID,
> newLength>. If it is FilePerBlock, we use FileChannel.truncate to truncate
> file to newLength directly. If it is FilePerChunk, we delete the files of the
> fully truncated chunks, and use FileChannel.truncate to process the partially
> truncated file. Then, in RocksDB, Datanode delete <TRUNCATING_blockid,
> newLength>, and put <TRUNCATED_blockid, newLength>.
