When this option is enabled, Impala cancels a query immediately when any of the nodes encounters an error,
rather than continuing and possibly returning incomplete results. This option is disabled by default, to help
gather maximum diagnostic information when an error occurs, for example, whether the same problem occurred on
all nodes or only a single node. Currently, the errors that Impala can skip over involve data corruption,
such as a column that contains a string value when expected to contain an integer value.
To control how much logging Impala does for non-fatal errors when <codeph>ABORT_ON_ERROR</codeph> is turned
off, use the <codeph>MAX_ERRORS</codeph> option.
