    Description

      There exists documentation that explains the steps to configure short-circuit reads
      https://ccp.cloudera.com/display/IMPALA10BETADOC/Configuring+Impala+for+Performance
      however, several occurrences of performance issues directly related to this misconfiguration have come up. To help avoid situations where the system is running in sub-optimal mode, a validation check could be put in place that would make the startup of impalad fail if the configuration settings are not correct. This would help prevent people from running unknowingly in a degraded mode.
