What are the common problems with CentOS HDFS configuration

Users may experience multiple issues when configuring Hadoop Distributed File System (HDFS) on CentOS. Here are some common problems and their solutions: Permissions issue: HDFS requires insufficient permissions to write to the directory, causing the local directory to work exceptionally. The solution is to view the log information in the Hadoop log folder, which is usually located in the /var/log/hadoop directory. The file owner is inconsistent: the file may be modified by ordinary users, or the file does not have corresponding permissions, which causes the root user to be unable to read or write. solve
