Kiran Kumar M R commented on HADOOP-11638:
------------------------------------------
I have attached a patch. Currently included only Linux and FreeBSD platform
specific code.
{code}
static unsigned long pthreads_thread_id(void)
{
unsigned long thread_id = 0;
#if defined(__linux__)
thread_id = (unsigned long)syscall(SYS_gettid);
#elif defined(__FreeBSD__)
thread_id = (unsigned long)pthread_getthreadid_np();
#endif
return thread_id;
}
{code}
> 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
> Components: native
> Affects Versions: 2.6.0
> Reporter: Dmitry Sivachenko
> Assignee: Kiran Kumar M R
> Attachments: HADOOP-11638-001.patch
>
>
> 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).
