I run a word count job on Hadoop.I have checked the HDFS and yarn were all in running before the job.but when the job started,hadoop jar /usr/local/hadoop/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.3.1.jar wordcount /input /output.
The job failed，seems like the master can't be connected.

I am using a Yarn EMR cluster through AWS. I am trying to write some tests for my codebase to ensure that I have test coverage for a Yarn connection.
Right now I am purposely making my connection fail by messing with the variable YARN_CONF_DIR. If the variable is set properly, I can connect to Yarn with no issue and run my job. However, when YARN_CONF_DIR is set but not to a path that has the expected xml, cfg, and bash files, I get the following output:

Now, I expected an error, of course. The weird thing is that you can see that the number of retries is looping, which I find odd. Look at the part of each line that says Already tried (x) time(s) and you can see it goes 0,1,2,3...9,0,1,2,3...9,0,1. I figured after retry #9 it would simply error and yield some sort of connection refused error. Instead, I am stuck in an infinite loop.
The command I am running is:
spark-submit --master yarn --deploy-mode cluster simple_spark_app_test.py
I also tried setting spark.yarn.maxAppAttempts to be 10 explicitly, but it doesn't affect the infinite looping. E.g. the command looked like
spark-submit --master yarn --deploy-mode cluster --conf spark.yarn.maxAppAttempts=10 simple_spark_app_test.py
Please note this only occurs if YARN_CONF_DIR is set but not to the right directory. If it is not set at all then it gives me an error that YARN_CONF_DIR must be set, as I would expect.
Running on Hadoop 2.6.0-cdh5.7.0 and issuing a simple Pig script.
After a successful job completion I'm getting the following message :
Seems like the workers are trying to communicate with each other (with a maximum of 3 retries) but I'm not sure why, and where this behavior is configured.
Does anyone know how to solve this issue ?

I've followed this guide to setup a simple cluster for Hadoop.
Though I can't see my slave node at http://master:50070.
I have followed the guide until Start the Yarn MapReduce Job tracker and everything is listed as it should when running jps on both master and slave node.
In the hadoop-hadoopuser-datanode-slave-1.log I see these messages over and over.

What am I missing?
This was solved by removing the line for 127.0.1.1 from /etc/hosts on both master and slave nodes.
Iam using single node hadoop cluster in ubuntu 13.10 with hadoop 1.2.1
Always iam having a problem like
whenever i restart my compueter and want to enter into hadoop environment
i login to terminal and type su
i get error like bin/su not in something
i do export /user/bin:/bin
then it works
then after getting into su
when i type hadoop fs -ls
i get error like trying 1..2...
lastly it failes

How can i aviod this 2 errors as
its very hard for me to format namenode always
First of all su has nothing to do with Hadoop. Next, you are getting these errors probably because you have not specified hadoop.tmp.dir property in your core-site.xml. The value of this property defaults to /tmp which gets emptied at each restart. Thus you loose all the HDFS metadata+data and have to reformat it.
It is always a good practice to add this property. Also, it is advisable to add dfs.name.dir and dfs.data.dir properties in your hdfs-site.xml files.
it seems like you have not set the password less login while installing hadoop it is recommended to set password less log in
for proper installation guide you can refer
http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
While moving a file in hadoop from temp directory
Used below command :-
[Divya#localhost hadoop]$ bin/hadoop dfs -copyFromLocal /tmp/gutenberg /home/Divya/gutenberg

Check whether namenode process is running on your localhost and on this port 54310
Check whether the hadoop daemon services are running properly. Use JPS command as root to check whether they are running properly. Make sure the cluster is properly set up.
