chiyang created PIG-3507:
----------------------------
Summary: It fails to run pig in local mode on a Kerberos enabled
Hadoop cluster
Key: PIG-3507
URL: https://issues.apache.org/jira/browse/PIG-3507
Project: Pig
Issue Type: Bug
Affects Versions: 0.10.0
Reporter: chiyang
It fails to run pig in local mode on a Kerberos enabled Hadoop cluster
*Command*
pig -x local <pig script>
*Pig script*
A = load '/etc/passwd';
dump A;
*Root cause*
When running pig in local mode, jobConf in HExecutionEngine is initiated with
core-default.xml (hadoop.security.authentication = simple), mapred-default.xml,
and yarn-default.xml. However, the settings are not passed to
UserGroupInformation. That's why obtainTokensForNamenodesInternal() is called
in obtainTokensForNamenodes(), and causes the exception to happen.
{noformat}
public static void obtainTokensForNamenodes(Credentials credentials, Path[] ps,
Configuration conf) throws IOException {
if (!UserGroupInformation.isSecurityEnabled()) {
return;
}
obtainTokensForNamenodesInternal(credentials, ps, conf);
}
{noformat}
*Error*
