Hadoop Primary Node Storage alarms

Previously only he adjusted the DFS storage directory to the maximum quota of directories, others were not processed (that is, in the default/directory, and the storage quota for this directory is only 50G)

Run a week less time, cluster start alarm, view is directory/storage occupies more than 60%

To see the specific directory situation, the main occupation of the directory has four, respectively:

/yarn 11G

/var 9.6G

/opt 4.7G

/usr 1.8G

which

Yarn mainly holds intermediate data related to Mr operation

var primarily stores log data for running and monitoring (/var/lib/cloudera-service-monitor)

Opt primarily stores CDH installation packages, including Repo,cache,parcels (where Repo,cache and run are irrelevant)

USR primarily stores installation files

Processing:

1. Adjust the monitoring log data storage path to a larger quota directory

2. Adjust yarn storage path to a larger quota directory
