Chris Nauroth commented on HADOOP-11638:
----------------------------------------
Thanks, Colin. While the previous code compiled on Mac, I'm not sure if anyone
knows whether or not it really worked. :-) We only use Mac as a deployment
environment and never as a real deployment environment (AFAIK), so it's quite
possible that no one noticed a problem. The revert was based on the fact that
the prior patch took us from a working Mac build (but possibly with bugs in
this part of the code) to a compilation failure.
Thanks for filing HDFS-7938.

> 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).
