IMPALA-14372: Output OpenTelemetry SDK Logs to Impala Logs
Emits log messages from the OpenTelemetry SDK to the Impalad DEBUG,
INFO, WARNING, and ERROR logs. Previously, these SDK log messages
were dropped.
Modifies the function of the 'otel_debug' startup flag. This flag
defaults to 'false' which causes log messages from the SDK to be
dropped. When set to 'true', log messages from the OpenTelemetry SDK
will be sent to the Impala logging system. The overall glog level is
applied to all messages sent from the OpenTelemetry SDK, thus DEBUG
SDK logs will not appear in the Impalad logs unless the glog level
is greater than or equal to 2.
When a trace is successfully sent to the OpenTelemetry collector,
zero log lines are generated. When a trace cannot be sent, local
testing showed 12 lines with a total size around 3k were written
between the impalad.ERROR and impalad.WARNING log files. The request
body is not included in these log messages unless the glog level is
greater than or equal to 2 thus log message size will not grow or
shrink based on the size of the trace(s).
This patch also removes the completely useless
'LoggingInstrumentation' class. Previously, the 'otel_debug' flag
caused this class to log messages, but those messages provided no
insightful information.
