------------------------------------
Summary: Case-sensitive use of configuration parameter
hbase.security.authentication
Key: HBASE-24190
URL: https://issues.apache.org/jira/browse/HBASE-24190
Project: HBase
Issue Type: Bug
Components: conf
Reporter: zhangbuzhang
In hbase-20586 (https://issues.apache.org/jira/browse/HBASE-20586)
（commit_sha: [https://github.com/apache/hbase/commit/cd61bcc0] ）
The code added
([SyncTable.java|https://github.com/apache/hbase/commit/cd61bcc0#diff-d1b79635f33483bf6226609e91fd1cc3])
for the use of *hbase.security.authentication* is case-sensitive. So users
setting it to “KERBEROS” won’t take effect.
private void initCredentialsForHBase(String zookeeper, Job job) throws
IOException {
Configuration peerConf = HBaseConfiguration.createClusterConf(job
.getConfiguration(), zookeeper);
if(peerConf.get("hbase.security.authentication").equals("kerberos")){
TableMapReduceUtil.initCredentialsForCluster(job, peerConf);
}
}
However, in current code base, other uses of *hbase.security.authentication*
are all case-insensitive. For example in *MasterFileSystem.java.*
public MasterFileSystem(Configuration conf) throws IOException {
...
this.isSecurityEnabled =
"kerberos".equalsIgnoreCase(conf.get("hbase.security.authentication"));
...
}
Users may misconfigured the parameter because of the case-senstive problem.
*How To Fix*
Using *eqaulsIgnoreCase* API consistently in every place when using
*hbase.security.authentication* or make it clear in Doc. (Current doc doesn't
mention it clearly)
