I'm self learning Hadoop and started of with installing Cloudera QuickVM on a VMware Workstation running CENT OS.
I was under the impression that Quickstart VM has most the of configurations predefined. Do I need to set up any other configurations to set up data and name node? Reason being when I type JFS I get only
[cloudera@quickstart bin]$ jps </n>
9480 RunJar </n>
18607 Jps 6952 </n>
org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar
I don't see any data nodes nor name nodes.I looked it up online and solution was to start the daemons using start-all.sh. But I get an error
[cloudera@quickstart hadoop]$ start-all.sh
bash: start-all.sh: command not found
Another round of research landed me in this
As suggested in that answer, when I ran bin/hadoop namenode -format
[cloudera@quickstart hadoop]$ bin/hadoop namenode -format
bash: bin/hadoop: No such file or directory
I'm stuck in the middle of nowhere with motivation for self study getting really low. Please help with a suggestion and raise up my spirits.
P.S.: I'm an extreme beginner on Hadoop, so please don't be harsh on me if the question looks stupid to you :)
Finally, I found out how to start services on cloudera quickstart vm with some help from the community.
service hadoop-hdfs-namenode start
Now when i run JPS, I can see all the daemons running,
[root@quickstart cloudera]# jps 2374 JobHistoryServer 2070 NameNode 3294 RunJar 4445 Bootstrap 4803 2947 -- process information unavailable 2196 SecondaryNameNode 1840 QuorumPeerMain 1908 DataNode 4836 3094 RunJar 3777 Master 2865 RESTServer 2594 ResourceManager 2327 Bootstrap 3663 Bootstrap 2451 NodeManager 1999 JournalNode 3111 Jps 3684 HistoryServer 4784 Bootstrap
Thanks a lot for your attention.
