             Summary: History Server "no histories" message to be dynamically generated by ApplicationHistoryProviders
                 Key: SPARK-11375
                 URL: https://issues.apache.org/jira/browse/SPARK-11375
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 1.5.1
            Reporter: Steve Loughran
            Priority: Minor


When there are no histories, the {{HistoryPage}} displays an error text which assumes that the provider is the {{FsHistoryProvider}}, and its sole failure mode is "directory not found"

{code}
Did you specify the correct logging directory?
Please verify your setting of spark.history.fs.logDirectory
{code}

Different providers have different failure modes, and even the filesystem provider has some, such as an access control exception, or the specified directly path actually being a file.

If the {{ApplicationHistoryProvider}} was itself asked to provide an error message, then it could
* be dynamically generated to show the current state of the history provider
* potentially include any exceptions to list
* display the actual values of settings such as the log directory property.
