When using the hs2 protocol with the http transport, include several
tracing http headers by default. These headers are:
* X-Request-Id -- client defined string that identifies the
http request, this string is meaningful only
to the client
* X-Impala-Session-Id -- session id generated by the Impala backend,
will be omitted on http calls that occur
before this id has been generated
* X-Impala-Query-Id -- query id generated by the Impala backend,
will be omitted on http calls that occur
before this id has been generated
The Impala shell includes these headers by default. The command
line argument --no_http_tracing has been added to remove these
headers.
The Impala backend logs out these headers if they are on the http
request. The log messages are written out at log level 2 (RPC).
Testing:
- manual testing (verified using debugging proxy and impala logs)
- new python test
