Hello,
I'm trying to configure HA for the HDFS namenode with QJM following the
instructions form here
http://hadoop.apache.org/docs/r2.2.0/hadoop-yarn/hadoop-yarn-site/HDFSHighAvailabilityWithQJM.html.
My setup is the following : Ubuntu 12.04.5 LTS on all the nodes, Hadoop 2.4.1
installed,
Hi,
We have a Hadoop cluster which is used by many users (students)
competing for resources.
We would like to prioritize jobs based on resource usage history per user.
Such functionality is common among classic HPC schedulers, e.g.
Hi,
may I know where should I find the sources related to speculative
scheduling happens ? and also how do we discard the output coming from
already completed mapper ?
I am actually trying to do something similar, like spawn map tasks
redundantly but not for speculative reasons but for each

Not rude at all. We were not born with any knowledge. We learn as we go. We
learn by asking. Capiche?

Dear List,
Just of curios, need to ask one thing.

Hi all,
when you divide up resources e.g. on CapacityScheduler or
FairScheduler etc., what does x% or resources mean? So, for example, a
guranteed 70% meant to indicate you can have up to
70% of the containers clusterwide irrespective of size of container
70% of the containers on each node
Actually, it's capisce.
And, obviously, we are all here because we are learning. But, now that
instructions have been posted again - I would expect that people would not
expect to have their
hands held to do something so simple as unsubscribe. They are supposedly
technologists. I would think they
My take on this item is that folks are too preoccupied with existence to be
bothered with a mail list that does not suit their specific needs. Or maybe too
impatient for knowledge. No sky is not falling-not yet anyway.

Trained as an electrical engineer I learned again and again from my
instructors: man is inherently lazy. Maybe that's the case. Also, some people
have complicated lives and need hand holding. It is best to accept people as
they are.

Possibly all have got their PHD degrees in hand on Hadoop and they don’t need
their group for knowledge sharing..
I think the best way to keep all the mates busy is asking the experts to share
their experiences, use cases.. help the new-comers…

Yes, I agree. We should accept people as they are.
So perhaps we should increase the hurdle to subscribe in the first place?
Something like adding a question like What do you do if you want to
unsubscribe from a mailing list?
That way the people who are lazy or need hand holding are simply unable
My take on this is simple. The owner/maintainer / administrator of the list
can implement a filter where if the subject of the email has word
unsubscribe . That email gets blocked and sender gets automated reply
stating that if you want to unsubscribe use the unsubscribe list.

Resources can mean memory-only (by default) or memory + CPU etc across the
_entire_ cluster.
So 70% of cluster resources for a queue means that 70% of the total memory set
for Hadoop in the cluster are available for all applications in that queue.
Heap sizes are part of the memory
Thanks -- so this would be enforced at the ResourceManager level and not
the NodeManager level.
