the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > to check the Flume for permissions, you can try the following steps:
1. Check whether the directory and file specified in the Flume configuration file exist, and the Flume user has read and write permission.
2. Check whether Flume users have sufficient permissions to access directories and files. You can run the following command to check Flume users:
ps -ef | grep flume
After executing the command, you should see output similar to this:
flume 1234 5678 0 08:00 ? 00:00:01 /usr/local/flume/bin/flume-ng agent -n myagent -c /etc/flume/conf.d -f /etc/flume/conf.d/myagent.conf
Where "flume" is the user when Flume is running.
3. If Flume uses Hadoop HDFS as the data source or data destination, check whether the machine where Flume resides has been authorized to users and groups of Hadoop HDFS so that they can access and write HDFS data. You can run the following command to check the group of Flume users:
groups flume
After executing the command, you should see output similar to this:
flume : flume hadoop
In the command, "flume" is the user of the Flume runtime, "flume" and "hadoop" are the groups to which the Flume runtime user belongs.
If you have checked the above steps and still cannot resolve the problem, you can try running Flume with a higher permission user to see if you can resolve the problem. If the problem persists, you can view the Flume log file to learn about the specific error information.
