[jira] [Created] (HADOOP-11638) Linux-specific gettid() used in OpensslSecureRandom.c

Dmitry Sivachenko created HADOOP-11638:
------------------------------------------

             Summary: Linux-specific gettid() used in OpensslSecureRandom.c
                 Key: HADOOP-11638
                 URL: https://issues.apache.org/jira/browse/HADOOP-11638
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.6.0
            Reporter: Dmitry Sivachenko


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).
