liyunzhang created HADOOP-16006:
-----------------------------------
Summary: Client use random ip when there are multiple ips even
setting dfs.client.local.interfaces when hostname is not set in kerberos
principle
Key: HADOOP-16006
URL: https://issues.apache.org/jira/browse/HADOOP-16006
Project: Hadoop Common
Issue Type: Bug
Reporter: liyunzhang
there are two ips, one is 10.8.180.90 other is 10.103.117.121
{code:java}
ifconfig

#hadoop version
Hadoop 2.7.1.2.4.2.98-1
{code}
I use kerberos. the principal is not specified hostname
{code}
klist
Ticket cache: FILE:/tmp/1artemis
Default principal: b_d...@apd.ebay.com
Valid starting Expires Service principal
12/14/18 15:02:28 12/15/18 01:02:28 krbtgt/apd.ebay....@apd.ebay.com
renew until 12/21/18 15:02:28
{code}
when i executed command like "hadoop fs -put /tmp/1236 /tmp/", there are some
possiblity that it will throw exception like
{code}

the problem here is as i did not provide hostname in my kerberos principal,
client use one of ip randomly
Client#setupConnection
{code}
private synchronized void setupConnection() throws IOException {
short ioFailures = 0;
short timeoutFailures = 0;
while (true) {
try {
this.socket = socketFactory.createSocket();
this.socket.setTcpNoDelay(tcpNoDelay);
this.socket.setKeepAlive(true);
/*
* Bind the socket to the host specified in the principal name of the
* client, to ensure Server matching address of the client connection
* to host name in principal passed.
*/
UserGroupInformation ticket = remoteId.getTicket();
if (ticket != null && ticket.hasKerberosCredentials()) {
KerberosInfo krbInfo =
remoteId.getProtocol().getAnnotation(KerberosInfo.class);
if (krbInfo != null && krbInfo.clientPrincipal() != null) {
String host =
SecurityUtil.getHostFromPrincipal(remoteId.getTicket().getUserName());
// If host name is a valid local address then bind socket to it
InetAddress localAddr = NetUtils.getLocalInetAddress(host);
if (localAddr != null) {
this.socket.bind(new InetSocketAddress(localAddr, 0));
}
}
}
{code}
#Here as i do not provide hostname in keytab , here socket will bind
one of my two ip
randomly to this.socket
{code}
NetUtils.connect(this.socket, server, connectionTimeout);
if (rpcTimeout > 0) {
pingInterval = rpcTimeout; // rpcTimeout overwrites pingInterval
}
this.socket.setSoTimeout(pingInterval);
return;
} catch (ConnectTimeoutException toe) {
/* Check for an address change and update the local reference.
* Reset the failure counter if the address was changed
*/
if (updateAddress()) {
timeoutFailures = ioFailures = 0;
}
handleConnectionTimeout(timeoutFailures++,
maxRetriesOnSocketTimeouts, toe);
} catch (IOException ie) {
if (updateAddress()) {
timeoutFailures = ioFailures = 0;
}
handleConnectionFailure(ioFailures++, ie);
}
}
}
{code}
I have added dfs.client.local.interfaces to hdfs-site.xml to force client use
eth0, but seems that there is some possiblity that Client will bind eth1 to
socket.
{code}
<property>
<name>dfs.client.local.interfaces</name>
<value>eth0</value>
</property>
