    The FSName system failed to boot is a fairly common error that Hadoop users get, especially when they first try to set up a Hadoop cluster at this point.

     05/13/23 04:11:37 AM ERROR namenode.FSNamesystem: Failed to initialize FSNamesystem.java.io.IOException: NameNode is not formatted.At org.apache.hadoop.hdfs.server.namesode.FSImage.recoverTransitionRead (FSImage.java:330)At org.apache.hadoop.hdfs.server.namesode.FSDirectory.loadFSImage (FSDirectory.java:100)At org.apache.hadoop.hdfs.server.namesode.FSNamesystem.initialize (FSNamesystem.java:411) 
         dfs.namesode.name.dir     file: /// data / 1 / dfs / nn 

    dfs.datanode.data.dir File storage location : /// data / 1 / dfs / dn

    The directory specified only in dfs.namesode.name.dir must indicate the NameNode status on the file system. The location of the directory specified in dfs.datanode.data must be found on all file systems in the DataNodes neighborhood.

    Otherwise, they will be displayed. Everyone stops the Hadoop process. Create the missing NameNode or DataNodes directories. Make sure the version is authorized correctly. Use the below commands for reference.

    On NameNode

     sudo mkdir-proizvodit  l / data / 1 / dfs / nnsudo chown -R hdfs: hdfs / data / 1 / dfs / nnsudo chmod six cents / data / 1 / dfs / nn 

    On Data Nodes

    error namenode.fsnamesystem fsnamesystem initialization failed

     sudo mkdir -p chown / data / 1 / dfs / dnsudo -R hdfs: hdfs / data / 1 / dfs / dn 

    After the directories are created normally, format the NameNode by running the following command through the entire NameNode.

     sudo -u hdfs hdfs namenode -format 

    You can now start the NameNode. After running the NameNode, check the logs to make sure you don’t see any errors. Once the NameNode has started, start all DataNodes fine.

    I am using Hadoop in pseudo-distributed mode on an Ubuntu VM. I recently decided to upgrade the RAM and the corresponding number of cores available for my virtual machine, and according to the experts, HDFs are fully plugged in. At first it was in safe mode and I manually shared the data with experts using:

    and almost all blocks were damaged or missing. So I thought it was just for my learning, I removed “/ user / msknapp” all over and displayed “/var/lib/hadoop-0.20/cache/mapred/mapred/.settings” all over. Thus, the section errors are gone. So nI’ll try it:

    So, I tried to stop and restart the name node and the date node. Failure:
