Client Login Failure

Possible Causes

• The krb5 file is not configured correctly in the client environment. This cause occurs only in security mode, but not normal mode.
• The username and password file used to access the HBase cluster are not configured in the hbase-site.xml configuration file of the client environment or the password file has expired. This cause occurs only in security mode, but not normal mode.
• The Jar packages in the client environment are inconsistent with those in the cluster.
• The time of the client environment is inconsistent with the time of the cluster and the difference is more than 3 minutes.

1. (Optional) In security mode, check whether the local krb5 configuration file is consistent with the that in the cluster.
   • Configuration file path in the Windows environment: C:\Windows\krb5.ini.
   • Configuration file path in the Linux environment: /etc/krb5.conf.

2. (Optional) In security mode, check whether the kerberos principal and keytab used for login are correct.
3. Check whether the time in the local environment is consistent with the that in the cluster.
4. Check whether the local jar packages are consistent with those of the cluster (especially the jar packages related to HBase, ZooKeeper, and Hadoop)
