Severity: critical
Affected versions:
- Apache Accumulo 2.1.0 before 2.1.1
Description:
Improper Authentication vulnerability in Apache Software Foundation Apache
Accumulo.
This issue affects Apache Accumulo: 2.1.0.
Accumulo 2.1.0 contains a defect in the user authentication process that may
That feature (ACCUMULO-489) had some fundamental flaws (ACCUMULO-826).
One of the arguments made when rolling that back, was that the feature
was not introduced in a minor release (it didn't appear in 1.4.0), so
it wasn't part of the 1.4 contract. I apologize for the
inconvenience this has caused.
I don't know that ACCUMULO-826 should be fixed before release, as I'm
not sure there's a good fix without changing the API, and these issues
may occur in several places in the MapReduce API.

I believe Accumulo can work across data centers, if the underlying DFS
span data centers. I also believe the latency tolerance is
configurable, and matters for servers holding locks in Zookeeper and
heartbeat messages to the Master. I'm not sure what the defaults for
these are, though.

You can still index a 1GB file... you just shouldn't try to push it
all in in a single mutation, nor should you try to store it using a
scheme that uses large keys.
You can even still store the whole raw file in Accumulo, particularly
if you chunk it up across multiple entries, but you may have

I would probably design the experiment to test different cluster sizes
as completely independent. That means, taking the entire thing down
and back up again (possibly even rebooting the boxes, and/or
re-initializing the cluster at the new size). I'd also do several runs
while it is up at a
