Increasing StateStore Timeout
If you have an extensive Impala schema, for example, with hundreds of databases, tens of thousands of tables, you might encounter timeout errors during startup as the Impala catalog service broadcasts metadata to all the Impala nodes using the StateStore service. To avoid such timeout errors on startup, increase the StateStore timeout value from its default of 10 seconds.
