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.
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.
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-${HADOOP_VERSION}.jar -d wordcount_classes
The hadoop version is 0.22.0 and this does not have a hadoop-core-0.22.0.jar though I find hadoop-hdfs-0.22.
Hey guys Montana here,
I have configured Hadoop for single node cluster, when I run my URLS, the .jsp's they work which means Hadoop is working but upon booting Hadoop by formatting a new distributed filesystem
Code:
bin/hadoop namenode -format
I get an SSH error, but then when I actually start Hadoop
Code:
bin/start-dfs.sh
Which should also handle the "${HADOOP_CONF_DIR}&q
Working it agrees http://www.ibm.com/developerworks/ru/library/l-hadoop-1/ at first I entered into the user of hadoop by means of a command
root@one: /volumes# su hadoop
The invitation was as a result displayed
root@one: /volumes#
and to check I entered into the user of hadoop executed the whoami command, on what gave out me hadoop.
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.
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/).
here is a commercial open source company, Cloudera, that supports and evangelizes Hadoop, and mainstream organizations and businesses ranging from the New York Times to IBM are using it...
