Redaction: Don't allow row logging when redaction rules are set
Redaction: Don't allow row logging when redaction rules are set

Row logging sends table data to the logs during query execution. Since
the log entries may be in an unexpected format, impalad will fail to
start if row logging and redaction would be enabled together. As an
example of an unexpected log format, a redaction rule might be triggered
by the column name "password" then redact the entire message, but with
row logging the data would be logged without the column name.
