Hi,
You can use Tableau. Link -http://tableausoftware.com/
But you need hive.

Not really performance monitoring but a simple charting tool. Scan a data

There are a few reasons to use map/reduce, or just map-only or
reduce-only jobs.
1) You want to do parallel algorithms where data from multiple machines
have to be cross-checked. Map/Reduce allows this.
2) You want to run several instances of a job. Hadoop does this reliably

You mean a performance monitoring tool? I have not used any, but you
should search for that, not graph.

Hi,
I am looking for some simple graphing tools to use with Hadoop (bar or line
chart). Most google searches for "hadoop graphing" turns up results for
much more complex graph analysis tool like Giraph.
Any simple rrdtool like solutions for Hadoop?
TIA,

Yes, I tested with smaller data sets and the MR job correctly reads/matches
one line at a time.

JT OOM??.. Refer https://issues.apache.org/jira/browse/MAPREDUCE-5508 (but
JT OOM should happen over a period of time. Not immediately).

Hi Arun,

I had the same heap size value, same no.of jobs,scheduler and it is works

Not yet updated in production environment. Will keep you posted once it is
done.
In which Apache hadoop release this issue will be fixed? Or this issue
already fixed in hadoop-1.2.1 version as in the given below link,

Please don't cross-post.
HADOOP_HEAPSIZE of 1024 is too low. You might want to bump it up to 16G or
more, depending on:
* #jobs
* Scheduler you use.

I assume you know the tradeoff here: If you do depend upon mapper slot # in
your implementation to speed it up, you are losing on code portability in
long term
That said, one way to achieve this is to use the JobConf API:
int partition = jobConf.getInt(JobContext.TASK_PARTITION, -1);

In Hadoop under the mapred-site.conf I can set the maximum number of mappers.
For the sake of this email I will call the number of concurrent mappers: mapper
slots.
Is it possible to figure out from within the mapper which mapper slot it is
running in?
On this project this is important becau

Thanks a lot and lot Antonio.
I'm using the Apache hadoop, hope this issue will be resolved in upcoming
apache hadoop releases.
Do I need the restart whole cluster after changing the mapred site conf as
you mentioned?

Hi Indrashish,
Can you please check if your you DN is accessible by nn , and the other

running the issue is DN is not able to attached to NN for getting register.
You can add DN in include file as well .
