saichanda created HDFS-14217:
--------------------------------
Summary: namenode and datanode are not starting
Key: HDFS-14217
URL: https://issues.apache.org/jira/browse/HDFS-14217
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode, namenode
Affects Versions: 2.9.2
Reporter: saichanda
Attachments: hadoop-saichanda-namenode-saichanda-OptiPlex-9020.log
I am new to hadoop ecosystem. I am setting up a cluster with 4 nodes, one
master and 3 slave nodes. I have done the ground work of updating all xml files
in hadoop/etc/hadoop folder. I saved the slaves file. I formatted the namenode.
I then started the cluster with command, sbin/start-dfs.sh. I get to see the
lines:
'starting namenode on localhost.... starting datanode on slave1...starting
datanode on slave2...starting datanode on slave3... starting secondary
namenode..... But when I run jps command in the terminal of masternode, I see
only Jps and Secondary Namenode. When I run jps command on the slave nodes, I
see only Jps, no datanode running on the slaves. What should I write in my
hdfs-site.xml? Currently I set the path for namenode and datanode like...
<value>file:/home/user/hadoop_store/hdfs/namenode<\value> and similarly for
datanode as well. In the log file for namenode, I see the line saying
"Inconsistent state: storage directory doesn't exist or not accessible for the
path /home/user/hadoop_store/hdfs/namenode.
