Repeated Reconnect Prompts When Connected to Impala

When connected to Cloudera Hadoop Impala, a reconnect message may appear every 5 to 10 minutes. For example:

Reconnect to federated.0ljz6ic0kor8k21axpx9z0k7z5x7?

Occasionally when reconnecting, another error may occur, which goes away after a few refresh attempts:

[Cloudera][ImpalaODBC] (110) Error while executing a query in Impala: [] :


  • Tableau Desktop
  • Cloudera Hadoop Hive


If the Kerberos authentication method is not used, customize the Impala connection using a .tdc file:
  1. Close all Tableau Desktop windows
  2. Save the attached .tdc file to Documents\My Tableau Repository\Datasources


AutoReconnect is disabled by default for Cloudera Hadoop Impala connections, because having this option enabled is not compatible with Impala connections using the Kerberos authentication method.
