By the way, something that I forgot to ask before:
Will the append implementation be as fast, as the write/copy functions?

Thanks, I exactly wanted to ask this for our R&D roadmap.

Or maybe more pessimistically, the second "stable" append
implementation.
It's not like HADOOP-1700 wasn't intended to work. It was just found
not
to
after the fact. Hopefully this reimplementation will succeed. If you're
running a cluster that contains mission-critical data that cannot
tolerate
corruption or loss, you shouldn't jump on the new-feature bandwagon
until
it's had time to prove itself in the wild.
But yes, we hope that appends will really-truly work in 0.21.
Experimental/R&D projects should be able to plan on having a working
append
function in 0.21.

Just to understand the road-map, 0.21 will be the first stable
"append"
implementation?

Hi.
Any idea when the "append" functionality is expected?
A working append is a blocker on HDFS 0.21.0.
The code for append is expected to be complete in a few weeks.
Meanwhile,
the rest of Common, HDFS, and MapReduce have feature-frozen and
need
to
be
stabilized and all of the critical bugs fixed. I'd expect the first
releases
of 0.21.0 in early November.

Also at "hadoop world nyc" http://cloudera.com/hadoop-world-nyc their
is going to be a presentation:
Low Latency, Random Reads from HDFS, Jay Booth, Elastic Platforms
That might be of interest to you.
