------------------------------
Summary: Revisit Windows socket API compatibility
Key: HDFS-7861
URL: https://issues.apache.org/jira/browse/HDFS-7861
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Thanh Do
Windows socket API is somewhat different from its POSIX counter part (as
described here: http://tangentsoft.net/wskfaq/articles/bsd-compatibility.html).
We should address the compatibility issue in this JIRA. For instance, in
Windows, {{WSAStartup}} should be called before any other socket APIs for the
APIs to work correctly. Moreover, as Winsock API does not return error code in
{{errno}} variables, {{perror}} does not work as in Posix systems. We should
use {{WSAGetLastErrorMessage}} instead.
