I am guessing you already asked if they could give you three 100MB files
instead? so you could parallelize the operation. or maybe your task
doesn't lend itself well to that.

it pretty reliable and of course it is asynchronously writing to that third
or fourth machine depending on replication factor.

There are 4 jobs submitted by the wordcount cassandra example and the first
one fails and the other 3 all pass and work with results.
The first job I noticed is looking for column name text0 due to i being 0
in the loop. The exception is not going through the wordcount code at all
though, but thi

I am trying to run the word count example and looking at the source, I
don't see where it knows which job tracker to connect to.
1. Would I be correct in guessing that I have to run hadoop jar ?
(just wondering why I don't see a port/hostname for job tracker in the
WordCount.java file)

I heard cassandra may be going the direction of removing super column and
users are starting to just use prefixes in front of the column.
The reason I ask is I was going the way of only using supercolumns and then
many tables were fixed with just one supercolumn per row as the structure
for that t
as to write it
themselves).
Any info on #1 and #2???

I was wondering something. Since I can take OPP and I can create a layer
that for certain column families, I hash the key so that some column
families are just like RP but on top of OPP and some of my other column
families are then on OPP directly so I could use lucandra, why not make RP

nope, just one and then it exits and quits(won't start up) and I can't
compile the code since the repository is down :(
I am working on web-tier setup and will come back hoping the cloudera
repository goes back online in the next day.(crossing my fingers).

I am also on sure why cassandra is doing a getLocalHost when I tried to bind
"everything" to 0
Ideally, we would want to have a replication factor of 4, and a minimum
write consistency of 2 (which looking at the default in cassandra.yaml is to
memory first with asynch to disk...perfect so far!!!)
Now, obviously, I can get the partitioner setup to make sure I get 2
replicas in each data cent

Is there a framework for stopping all nodes/starting all nodes for
cassandra? I am okay with something like password-less ssh setup that
hadoop scripts did...just something that allows me to start and stop the
whole cluster.
