eclipse plugin for hadoop 0.22.0

linux-howto

http://serverfault.com – I am using Eclipse Indigo Service Release 2 and hadoop 0.22.0 on win 7. Trying to use the eclipse plugin provided in the Hadoop package but that does not seem to work. When I try adding a new Hadoop Location, i get an error stating "Error: Server IPC Version 5 cannot communicate with client version 3". I cant compile eclipse from hadoop distribution 0.22.0 as there is no source available. Any help would be highly appreciated. P.S: All this only for testing/learning purpose and to create a small POC for my manager (HowTos)

Hey guys Montana here,

I have configured Hadoop for single node cluster, when I run my URLS, the .jsp's they work which means Hadoop is working but upon booting Hadoop by formatting a new distributed filesystem

Code: bin/hadoop namenode -format I get an SSH error, but then when I actually start Hadoop

Code: bin/start-dfs.sh Which should also handle the "${HADOOP_CONF_DIR}&q

cp not working in script 41 weeks 4 days ago

Ok, this is the first script I've ever attempted to write so go easy on me. I'm just trying to simple copy a tar.gz file from the directory the script is located to /usr/local/filename.tar.gz The script is run as root so it shouldn't be a permissions issue.

Mapreduce Compilation in Java 19 weeks 5 days ago

I am following this tutorial.

http://hadoop.apache.org/docs/mapreduce/current/mapred_tutorial.html

javac -classpath ${HADOOP_HOME}/hadoop-core- ${HADOOP_VERSION}.jar:${HADOOP_HOME}/hadoop-mapred-${HADOOP_VERSION}.jar:${HADOOP_HOME}/hadoop-hdfs-${HADOOP_VERSION}.jar -d wordcount_classes

The hadoop version is 0.22.0 and this does not have a hadoop-core-0.22.0.jar though I find hadoop-hdfs-0.22.

Full list of error:

i want to access hbase table from hadoop mapreduce....i m using windowsXP and cygwin i m using hadoop-0.20.2 and hbase-0.92.0 hadoop cluster is working fine....i am able to run mapreduce wordcount successfully on 3 pc's hbase is also working .....i can cerate table from shell

i have tried many examples but they are not working....when i try to compile it using javac Example.java

it gives error..

I am required to hack a single node hadoop "cluster" (cloudera psuedo-distributed) to be able to access it remotely. I have successfully installed hadoop and I have updated the localhost identifiers in the configs to the IP address of the machine. I can run hadoop fs -ls / and all is good. I have created a passphraseless key and I can ssh to the hadoop machine.

Despite an error specified on Error of start of the demon of Namenode with a log of errors me it was succeeded to execute a command

./hadoop fs - mkdir/user/hadoop

and to create the appropriate folder (that the command confirmed ./hadoop fs - lsr/).

I am working with Hadoop 1.0.3 on Ubuntu 12.04, Eclipse 3.7 and am developing a GUI to execute Hadoop jobs using Windowbuider Pro. I need to execute the jar files containing my codes from the GUI. I have used the runtime.getruntime.exec() method with some success.

I've setup Hadoop to use Kerberos (following the Cloudera security guide), but it is unclear how I connect to hadoop with regular users (e.g. username=myuser).

Currently I have myself authenticated with Kerberos with my Keberos admin user (via kinit kerbadmin/admin), but that doesn't seem to help. Do I need to tell Hadoop that kerberos user "kerbadmin" is allowed to use Hadoop?
