They announced a “scheduled” downtime with 1 day notice “due to a system-wide upgrade and rollout of a new version of our storage cluster.” Co-incidentally there’s a post on the Hadoop mailing list by their developer…
I am running Hadoop 0.7.2 in a production environment and it has stored
~170GB of data.
I am using 4 nodes with 1.3TB storage each and the master node is not being
used for storage.
Couple of days back, I noticed an error where Hadoop was not accepting new
files, I mean the upload always failed, but download was still working
I read in the mailing list that this issues is resolved in 0.9.0, but I am a
bit skeptical about moving to 0.9.0 as I don’t know whether I will end up
loosing the files that are already stored. Kindly confirm this and I wil
move to 0.9.0 and also please tell me the steps or pre-cautions I should
take before moving to 0.9.0.
Seems like a lot of users are having problems uploading files on their support forum.
Hey and 4 months ago there’s apparently 30 nodes… Glad I’m out of the company.
