----------------------------------------
Summary: Log kinit output in credential renewal thread
Key: HADOOP-15382
URL: https://issues.apache.org/jira/browse/HADOOP-15382
Project: Hadoop Common
Issue Type: Improvement
Components: security
Reporter: Wei-Chiu Chuang
We currently run kinit command in a thread to renew kerberos credentials
periodically.
{code:java}
Shell.execCommand(cmd, "-R");
if (LOG.isDebugEnabled()) {
LOG.debug("renewed ticket");
}
{code}
It seems useful to log the output of the kinit too.
