Hi all,

This issue may be considered fixed once the new storage cluster has been
announced. I¹m copying the announce:

‹‹‹‹‹

Dear FIWARE Lab user,
Few months ago our Big Data team started working on deploying a new global
instance of Cosmos. The current "old" one is reaching its limit, both in
storage and computing capabilities, so moving to a large and powerful
cluster was a need.
Regarding this new instance, we have decided to split storage and
computing into two different clusters. That's why I'm glad to announce the
storage one is ready to be used. Nevertheless, some remarks must be done:

• It must be considered as a beta. Errors and missconfigurations may still
  arise.

• It is only suited for storage purposes. The software stack only
  comprises HDFS, not MapReduce nor any other computing tool.

• No ssh access has been enabled. From the current "old" cluster we have
  learn most of people used the ssh access to install their own software or
  allocating vast ammounts of data in the local file system, which is a very
  bad behaviour since the clusters are always shared. Thus, the only allowed
  access is through WebHDFS REST API, which is protected by OAuth2.

This cluster, and the upcoming computing one, will replace the current
"old" cluster in the short time, based on a modern Hadoop distribution.
Nevertheless, for now it is not mandatory to use it. Moving to this
cluster is only recommended:

• If you are interested on pure storage (i.e. no analytics on the data,
  for instance, if you are using Cygnus for building historics about Orion's
  context data)

• and, as much, the consumption of your data is done through WebHDFS REST
  API.

It must be said those of you moving right now to this cluster will enjoy a
larger HDFS quota. If you are interested, please sent an email to
francisco.romerobueno@telefonica.com
Any doubt you may have, do not hesitate to contact us.
Best regards,
Cosmos Big Data team

Any update? still impeded? Thanks

Hi all,

Regarding this issue, it must be said the new cluster for storage is
finally working. This new cluster is based on a modern Hadoop and the
problem regarding offsets in WebHDFS should be fixed.

As said, this cluster is only suited for storage, not computing (a second
cluster specifically addressing computing will be released in a few
weeks). So, if your use case is about storing data in HDFS and consuming
it through WebHDFS, with no Hive, no MapReduce, then you are ready to move
from the ³old² cluster (cosmos.lab.fiware.org) to the new one
(storage.cosmos.lab.fiware.org). If you are interested, let me now and
I¹ll provision the account and I¹ll migrate the data from one cluster to
the other.

Regards,
Francisco

Adding impediment: the user is waiting for the new cluster deployment.

The deployment started several months ago, this is a very ambitious task.
We are in the latest steps, most probably it will be ready after the Xmas
holidays.

Francisco
