> Append should be easy if we have variable length block support from
> HDFS-3689, i.e., the new data will be appended to a new block. We need to
> revisit whether and how to support appending data to the original last block.
> 1. Append to a closed striped file, with NEW_BLOCK flag enabled (this)
> 2. Append to a under-construction striped file, with NEW_BLOCK flag enabled
> (HDFS-9173)
> 3. Append to a striped file, by appending to last block group (follow-on)
> This jira attempts to implement the #1, and also track #2, #3.
