MAX_ERRORS

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.

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

Default: 0 (meaning 1000 errors)
