             Summary: Spread WAL across multiple data directories
                 Key: KUDU-2975
                 URL: https://issues.apache.org/jira/browse/KUDU-2975
             Project: Kudu
          Issue Type: New Feature
          Components: fs, tablet, tserver
            Reporter: LiFu He
         Attachments: network.png, tserver-WARNING.png, util.png

Recently, we deployed a new kudu cluster and every node has 12 SSD. Then, we 
created a big table and loaded data to it through flink.  We noticed that the 
util of one SSD which is used to store WAL is 100% but others are free. So, we 
suggest to spread WAL across multiple data directories.
