How to load the output data of a mapreduce program which is in the hadoop file system into hbase?
Tried using PIG command,but found error.
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-${HADOOP_VERSION}.jar -d wordcount_classes
The hadoop version is 0.22.0 and this does not have a hadoop-core-0.22.0.jar though I find hadoop-hdfs-0.22.
Ok, this is the first script I've ever attempted to write so go easy on me. I'm just trying to simple copy a tar.gz file from the directory the script is located to /usr/local/filename.tar.gz The script is run as root so it shouldn't be a permissions issue.
Hey guys Montana here,
I have configured Hadoop for single node cluster, when I run my URLS, the .jsp's they work which means Hadoop is working but upon booting Hadoop by formatting a new distributed filesystem
Code:
bin/hadoop namenode -format
I get an SSH error, but then when I actually start Hadoop
Code:
bin/start-dfs.sh
Which should also handle the "${HADOOP_CONF_DIR}&q
HBase stable
(http://apache.cs.utah.edu/hbase/stable/)
is currently hbase-0.90.4, what version(s) of HDFS is it compatible with?
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.
Virtualization giant VMware has unveiled Spring Hadoop, which integrates its Spring Framework with the Apache Hadoop platform.
