test_libhdfs_write.c: In function ‘main’:
test_libhdfs_write.c:28:37: warning: initialization makes pointer from integer
without a cast [enabled by default]
struct htrace_conf *test_conf =
htrace_conf_from_str(HTRACE_SPAN_RECEIVER_KEY "=htraced;"
{code}
I'm not sure why you would be getting this warning, since none of those
parameters are integers. My guess would be that there is a problem with the
test program. Where are you including htrace.h from?
bq, htraced.c uses hexdump defined in test.c. The code in htraced.c seems to be
garbage of try-and-error.
Good catch. It should not be using hexdump since that is only for testing.
There are other log messages in that file that should not be there. I'll see
if I can create a unit test that verifies that we don't have unresolved
dependencies in the library.
bq, I think it would be kind to use default such as "localhost:9095".
Yeah, that makes sense.
bq. I got tons of cbuf_used messages.
Yeah, let me remove those
bq. Yeah. We could add some notes for testing to BUILDING.txt
Good idea
