How Do I Delete Residual Table Names in the table-lock Directory of ZooKeeper?

Symptom

In Kerberos authentication is enabled for the cluster (in security mode), how can I clean up the residual table names created due to table creation failures under the table-lock node in ZooKeeper (the default path is /hbase/table-lock)?

Procedure

1. On the client, run the kinit command as the hbase user to obtain a security certificate.
2. Run the following command to launch the ZooKeeper Command Line Interface (zkCLI).

   hbase zkcli

3. Run the following command on the zkCLI to check whether the table name of the table that fails to be created exists.

   ls /hbase/table

   • If the table name exists, no further operation is required.
   • If the table name does not exist, run the following command to check whether the table name of the table fail to be created exist.

     ls /hbase/table-lock

     If the table name exists, run the following command to delete the table name.

     delete /hbase/table-lock/<table>

     <table> indicates the residual table name.
