Hi!
I need to test my hadoop code on a cluster,
what is the simplest way to do this on the cloud?
Is there any way to do it for free?
Thank in advance
Hi,
I'm using Hadoop Pipes and I want to chain two jobs (job1 and job2). Is it
possible?
I use the FileInputFormat.addInputPath()
and FileOutputFormat.setOutputPath() functions to do it in Java, but I want
to know if there is some way for do it in C++ with pipes.
Thanks in advance,
Massimo
I think you can test it in Amazon EC2 with pseudo distribute, it support 1 tiny
instance for 1 year free.

You can check Amazon Elastic MapReduce, which comes preconfigured on EC2
but you need to pay a little por it, or make your custom instalation on EC2
(beware that EC2 instances come with nothing but really basic shell tools
on it, so it may take a while to get it running).
Amazon's free tier allows
I've been dealing with a similar situation and I haven't found other
solution rather than launching two independent jobs (with a script or
whatever you like), letting the output of the first be the input of the
last. If you find any other option please let me know.

As a slightly more advanced option for OpenStack people: Consider trying
savanna (Hadoop provisioned on top of open stack) as well.

Yes, of course. It's a solution but I need all jobs in a single file like
in java.. Can anyone help me?

Setting
conf.set("yarn.resourcemanager.connect.max-wait.ms", "500");
conf.set("yarn.resourcemanager.connect.retry-interval.ms", "500");
still results in a wait of around 15 seconds. Setting this:
conf.set("ipc.client.connect.max.retries", "2");
Also does not help. Is there a retry para
What's the value for "io.compression.codecs" config parameter ?

Hi Emmanuel, log aggregation now only aggregates finished apps logs onto
hdfs. there's no way as of now to support running apps. that'll be a to-do
feature in the feature.

For the codecs, you can choose
among org.apache.hadoop.io.compress.*Codec. LzoCodec has been moved out of
Hadoop (see HADOOP-4874).

Hi All,
I don't know why the journal node logs has this weird "NoClassDefFoundError:
org/apache/hadoop/hdfs/server/namenode/FSImage" exception.
This error occurs each time I switch my namenode from standby to active

Dear All,
Sorry, I found the root cause for this problem, it appears that I overwrite the
hadoop-hdfs-2.2.0.jar with my own custom jar, but forgot to restart the journal
node process,
so the process cannot find the FSImage class, but it actually there inside my
custom jar.
