5.1.6. NameNode edit logs directory status

This host-level alert is triggered if the NameNode cannot write to one of its configured edit log directories.

 5.1.6.1. Potential causes
  • At least one of the multiple edit log directories is mounted over NFS and has become unreachable

  • The permissions on at least one of the multiple edit log directories has become read-only

 5.1.6.2. Possible remedies
  • Check permissions on all edit log directories

  • Use the dfs.name.dir parameter in the hdfs-site.xml file on the NameNode to identify the locations of all the edit log directories for the NameNode. Check whether the NameNode can reach all those locations.
