Question

以下代码

private def deleteTable(tableName: String): Unit = {
 val tableNames = admin.listTableNames()
    println(s"HBase has the following tables: ${tableNames.map(_.toString).toList}")
    tableNames.find(_.getNameAsString == tableName) match {
      case Some(matchedTableName) =>
        admin.disableTable(matchedTableName)
        admin.deleteTable(matchedTableName)
        println(s"Table $tableName was found in HBase and deleted.")
      case None => println(s"Table $tableName was not in HBase.")
    }
}

会抛出

17/10/02 20:45:22 ERROR ApplicationMaster: User class threw exception: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hbase.TableNotFoundException): XXXX

这对我没有意义，因为可以从管理员检索表名，但是当禁用它时，突然无法找到该表。

编辑：在HBase shell上，我试过

hbase(main):011:0> user_permission 'XXXX'
User                                                         Namespace,Table,Family,Qualifier:Permission                                                                                                                                      

ERROR: DISABLED: Security features are not available

当表存在时，HBase抛出TableNotFoundException
