Change subject: IMPALA-9609: Minimize Frontend activity in executor only impalads ...................................................................... IMPALA-9609: Minimize Frontend activity in executor only impalads Until now the Frontend started fully regardless of flag is_coordinator, e.g. created connections to the HMS, which is both error prone and can DoS the metastore. Executor only impalads still need a JVM as queries can contain java calls (HDFS/Hbase API calls, Hive UDFs).
