Raghu Angadi commented on HADOOP-5332:
--------------------------------------
Should datanode clean up tmp directory if this config is false (HADOOP-5225)?
Seems required to match decisions made in 0.19.1 and 0.18. Otherwise users are
not completely isolated.
Also should the default used in FSNamesystem.java for dfs.support.append to
false?
> Make support for file append API configurable
