Change subject: [PROTOTYPE] IMPALA-10711: Allow customizing startup's filesystem check ...................................................................... [PROTOTYPE] IMPALA-10711: Allow customizing startup's filesystem check At startup, Impala runs JniFrontend::checkFileSystem() to verify that it can list the root directory of the filesystem. Some deployments would like to restrict Impala to a subdirectory of the filesystem. In that circumstance, Impala may not have access to the root of the filesystem and the startup check will fail. This adds the startup parameter: startup_filesystem_check_directories to specify the directories to check in JniFrontend::checkFileSystem() at startup. For deployments that are restricted to a subdirectory, startup_filesystem_check_directories=/some/subdirectory would check /some/subdirectory rather than /. This parameter allows for a list of directories in case it is useful to verify multiple locations (such as different s3 buckets). If set to the empty string, no directories will be checked.
