    Description

      It is possible to create a Kudu table containing unicode characters in its in Impala by specifying the kudu.table_name attribute. When trying to select from this table you receive an error that the underlying table does not exist.

      The example below shows a table being created successfully, but failing on a select * statement.

      [jh-kafka-2:21000] > create table test2( a int primary key) stored as kudu TBLPROPERTIES('kudu.table_name' = 'impala::kudutest.😀');
      Query: create table test2( a int primary key) stored as kudu TBLPROPERTIES('kudu.table_name' = 'impala::kudutest.😀')
      WARNINGS: Unpartitioned Kudu tables are inefficient for large data sizes.Fetched 0 row(s) in 0.64s
      [jh-kafka-2:21000] > select * from test2;
      Query: select * from test2
