Colin Patrick McCabe created HDFS-3676:
------------------------------------------
Summary: handleSaslConnection failure doesn't try to renew the
correct UGI
Key: HDFS-3676
URL: https://issues.apache.org/jira/browse/HDFS-3676
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.1.0-alpha
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
Client.java has this code:
{code}
private synchronized void handleSaslConnectionFailure(
final int currRetries, final int maxRetries, final Exception ex,
final Random rand, final UserGroupInformation ugi) throws IOException,
InterruptedException {
ugi.doAs(new PrivilegedExceptionAction<Object>() {
public Object run() throws IOException, InterruptedException {
final short MAX_BACKOFF = 5000;
closeConnection();
disposeSasl();
if (shouldAuthenticateOverKrb()) {
if (currRetries < maxRetries) {
if(LOG.isDebugEnabled()) {
LOG.debug("Exception encountered while connecting to "
+ "the server : " + ex);
}
// try re-login
if (UserGroupInformation.isLoginKeytabBased()) {
UserGroupInformation.getLoginUser().reloginFromKeytab();
} else {
UserGroupInformation.getLoginUser().reloginFromTicketCache();
}
{code}
It's not renewing the UGI that had the problem, it's renewing the loginUser.
