| <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> |

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