title: Auto execution of "validate metadata" in Impala
body: <p>I have Tableau connected to Cloudera Impala data. The table I am reading from Metastore keeps on updating so, when I want the viz to update (pressing F5) I have to go to Impala in Cloudera and execute "INVALIDATE METADATA" before refreshing the viz. I know this can be done using the connection to Hive Server 2, but it takes a long time to execute the query. My question is there anyway to automatically execute "validate metadata" and "Refresh" queries in Impala Cloudera?</p>
  
  <p>Thanks,</p>
