Description

Currently, multi-append (serializable) can cause write the incorrect content.
Reproduction method:

1. Open a file with O_APPEND flag in encryption zone directory.
2. Call hdfsWrite() twice.
3. Then read all file contents => only the first write content is correct.

So we need to fix it.
