Colin Patrick McCabe commented on HADOOP-11638:
-----------------------------------------------
Thanks for that clarification, [~dankm]. That sounds like an internal
implementation issue of the {{pthread_getthreadid_np}} function on FreeBSD and
possibly even a kernel-level detail. If FreeBSD later supplies an API for
getting longer numeric thread IDs than 32-bits, we can think about switching
over to it then. But for now we have to use the OS-provided API that exists.
Committed to 2.7. Thanks, all.

> In OpensslSecureRandom.c you use Linux-specific syscall gettid():
> static unsigned long pthreads_thread_id(void)
> {
> return (unsigned long)syscall(SYS_gettid);
> }
> Man page says:
> gettid() is Linux-specific and should not be used in programs that are
> intended to be portable.
> This breaks hadoop-2.6.0 compilation on FreeBSD (may be on other OSes too).
