RE: Unable to use hadoop cluster on the cloud

2011-03-06 Thread praveen.peddi

Yes all versions are the same. I installed hadoop on master and copied the 
folder to other machines so the install should be identical.

BTW I resolved the below issue by making all slaves visible to the client 
machine. Previously only master was visible to the client.

However I have another problem when running the job. For some reason the slave 
host names are resolved to different names than the ones I gave in hadoop 
config.

Each vm has two nic cards. I configured eth1 as hslave1, hslave2 eth0 is 
not used by hadoop at all but when running the job it is somehow resolving 
slave name as machine name instead of hslave1 and that is causing 
communication issues between slaves I think. I even specified property 
mapred.tasktracker.dns.interface to eth1 but that didn't help.

I saw that one can also specifiy slave.host.name property but I am trying to 
avoid that since that would change the hadoop install on each slave.

Any thoughts to resolve the issue would be appreciated...

Are you sure that all the version of hadoop are the same?

 Thanks Adarsh for the reply.

 Just to clarify the issue a bit, I am able to do all operations
 (-copyFromLocal, -get -rmr etc) from the master node. So I am confident that
 the communication between all hadoop machines is fine. But when I do the
 same operation from another machine that also has same hadoop config, I get
 below errors. However I can do -lsr and it lists the files correctly.

Praveen, Your error is due to communication problem between your 
datanodes i.e Datanode1 couldn't able to place the replica of a block 
into coresponding datanode2.

U mention the HDFS commands.

Simply check from datanode1 as

ssh datanode2_ip or
ping datanode2_ip

Re: LZO Packager on Centos 5.5 fails

2011-03-06 Thread phil young

Thanks for the responses.

Saurabh,
  Thanks for the response. I got LZO installed without the packager, but I
do appreciate the help as the rpm method seems like a better way to go.

Pete,
  The clusters are all 64-bit machines. That doesn't matter at this point
because I was able to get this to work without the packager by reading many,
many web pages. I had wanted to use the packager because I assumed it would
resolve open questions like: if the code evolved from
GoogleCode-KevinWeil-ToddLipconn, and the GoogleCode says to use branch
0.1 because the trunk is for the new Hadoop APIs (which Hive doesn't use
yet), then what's the right thing to install.

I do have LZO working now with Hive. Tables can now be compressed as LZO,
with Indexes, with data validated via lzop directly, and I can use
intermediate LZO compression. That took more work than I anticipated, so I'm
still interested in the packager.


To sum up what I've done:
I replaced wget with wget --no-check-certificate in run.sh.

I did replace the string in the file you mentioned, but the only file with
that name is in the build directory
[root@adhocmaster01an hadoop-lzo-packager]# find ./ -name
*toddlipcon-hadoop-lzo.spec*
./build/topdir/SPECS/toddlipcon-hadoop-lzo.spec

Unsurprisingly, executing run.sh again yielded the original error message.
It seems I should be able to change the version tag upstream somewhere,
but I don't have enough time now to research SPEC files and how deep this
rabbit hole might go.

I do appreciate the body of work that this is all built on and your
responses, but I am surprised that there isn't a more comprehensive set of
How-Tos. I'll assist in writing up something like that when I get a chance.
Are other people using CDH3B3 with 64-bit CentOS/RedHat, or is there
something I'm missing?

Thanks for the assistance.
