Hi Kishore,
As per the exception given, Node Manager is getting excluded. It might be
happening that you have configured the Node Manager in excluded file using
this configuration in Resource Manager.
Could you check this configuration in RM, is it configured with any file
and that file
Using InputFormat under mapreduce package. mapred package is very old
package. but generally you can extend from FileInputFormat under
o.a.h.mapreduce package.

If you really want this you have to switch to hadoop 2.x.
See this JIRA.

Ok just read the JIRA in detail (pays to read these things before posting). It
says:
Append is not supported in Hadoop 1.x. Please upgrade to 2.x if you need
append. If you enabled dfs.support.append for HBase, you're OK, as durable sync
(why HBase required dfs.support.append) is now enabled
The answer to the delta part is more that HDFS does not presently
support random writes. You cannot alter a closed file for anything
other than appending at the end, which I doubt will help you if you
are also receiving updates (it isn't clear from your question what
this added data really is).
Hi,
If you are looking to make it ignore those files, you can probably
consider using the -i flag.

If it is 1k new records at the end of the file then you may extract
them out and append the existing file in HDFS. I'd recommend using
HDFS from Apache Hadoop 2.x for this purpose.

Hi Devaraj,
Thanks for pointing me to this RC. I am trying this out, and getting
this error for NM to get started. My RM is running fine, but NM is failing
and saying that it is disallowed by RM and received a SHUTDOWN message.
Please give me clue to resolve this.

I've seen mentioned that you can access HDFS via ClientProtocol, as in:
ClientProtocol namenode = DFSClient.createNamenode(conf);
LocatedBlocks lbs = namenode.getBlockLocations(path, start, length);
But we use:
fs = FileSystem.get(URI, conf);
filestatus = fs.getFileStatus(path);
Hi :
Is there a hadoop 2.0 tutorial for 1.0 people ? Im used to running
start-all.sh , but it appears that the new MR2 version of hadoop is much
more sophisticated.
In any case, Im wondering what the standard way to start the new generation
of hadoop/mr2 hadoop/mapreduce and hadoop/hdfs is and
@Robin East : Thank you for keeping me updated. I was on 1.0.3 when I had
tried append last time and it was not working despite of the fact that API
had it. I tried it with 1.1.2 and it seems to work fine.
@Manickam : Apologies for the incorrect info. Latest stable release(1.1.2)
supports
The append in 1.x is very broken. You'll run into very weird states
and we officially do not support it (we even call out in the config as
broken). I wouldn't recommend using it even if a simple test appears
to work.

I totally agree harsh. It was just to avoid any misinterpretation :). I
have seen quite a few discussions as well that talk about the issues.
I would strongly recommend to switch from 1.x if append is desired.
Warm Regards,

These APIs (ClientProtocol, DFSClient) are not for Public access.
Please do not use them in production. The only API we care not to
change incompatibly are the FileContext and the FileSystem APIs. They
provide much of what you want - if not, log a JIRA.

Hi,
I would like to ask a few questions on how to debug Hadoop.
First I'll explain what I'm trying to do.
I'm doing my graduation thesis.
Are group is starting an implementation on a voluntary environment. For
this it is very important to have all the results signed so that we can
guarantee that
I am new to hadoop, just started reading 'hadoop the definitive guide'.
I downloaded hadoop 1.1.2 and tried to run a sample Map reduce job using
cygwin, but I got following error
java.io.IOException: Failed to set permissions of path:
hadoop fs -chmod -R 755 \tmp\hadoop-Sudhir\mapred\staging
Then It should works.
