    <p>
      <indexterm audience="hidden">MAX_ERRORS query option</indexterm>
      Maximum number of non-fatal errors for any particular query that are recorded in the Impala log file. For
      example, if a billion-row table had a non-fatal data error in every row, you could diagnose the problem
      without all billion errors being logged. Unspecified or 0 indicates the built-in default value of 1000.
    </p>

    <p>
      This option only controls how many errors are reported. To specify whether Impala continues or halts when it
      encounters such errors, use the <codeph>ABORT_ON_ERROR</codeph> option.
    </p>

    <p>
      <b>Type:</b> numeric
    </p>

    <p>
      <b>Default:</b> 0 (meaning 1000 errors)
