Anbang Hu commented on HADOOP-15467:
------------------------------------
As the stack trace indicates, both tests get stuck in getCanonicalHostName() in
InetAddress.java.
{code:java}
/**
* Gets the fully qualified domain name for this IP address.
* Best effort method, meaning we may not be able to return
* the FQDN depending on the underlying system configuration.
*
* <p>If there is a security manager, this method first
* calls its {@code checkConnect} method
* with the hostname and {@code -1}
* as its arguments to see if the calling code is allowed to know
* the hostname for this IP address, i.e., to connect to the host.
* If the operation is not allowed, it will return
* the textual representation of the IP address.
*
* @return the fully qualified domain name for this IP address,
* or if the operation is not allowed by the security check,
* the textual representation of the IP address.
*
* @see SecurityManager#checkConnect
*
* @since 1.4
*/
public String getCanonicalHostName() {{code}
After native method call getHostByAddr, it takes a long time to return the
domain name. I am guessing daily Windows builder does not belong to a domain
whose canonical name resolution takes a long time.
