Dan Burkert commented on KUDU-2294:
-----------------------------------
Hi [~alexhofsteede], how did you install Impala and Kudu, do you have Kerberos
authentication enabled in Kudu, and are the nodes which host Impala Daemons and
Kudu Servers the same, or are there Impala daemon nodes which don't have kudu
servers installed?
> RPC negotiation from Impala to Kudu fails
> -----------------------------------------

> Key: KUDU-2294
> URL: https://issues.apache.org/jira/browse/KUDU-2294
> Project: Kudu
> Issue Type: Bug
> Components: impala
> Affects Versions: 1.4.0
> Environment: 4.4.0-72-generic #93~14.04.1-Ubuntu
> Reporter: Alex Hofsteede
> Priority: Minor
>
> When connecting to Kudu from Impala (impalad version 2.8.0-cdh5.11.1) I am
> able to successfully use DDL queries to create tables in Impala backed by
> Kudu. eg:
> {code:java}
> CREATE TABLE test_kudu (id BIGINT, name STRING, PRIMARY KEY (id)) PARTITION
> BY HASH (id) PARTITIONS 2 STORED AS KUDU TBLPROPERTIES ('kudu.table_name' =
> 'test_kudu', 'kudu.master_addresses' = '172.19.42.1',
> 'kudu.num_tablet_replicas' = '1' );
> {code}
> This successfully creates the table in Kudu, However when I try and query
> this table, I get this error in the impala shell:
> {code:java}
> [88b9db42e0f5:21000] > SELECT * FROM test_kudu;
> Query: select * FROM test_kudu Query submitted at: 2018-02-09 00:21:35
> (Coordinator: http://88b9db42e0f5:25000) Query progress can be monitored at:
