Kudu installation
I am installing apache kudu to try it out.
The installation instructions state the following:
Apache Kudu has tight integration with Apache Impala (incubating), allowing
you to use Impala to insert, query, update, and delete data from Kudu
tablets using Impala's SQL syntax, as an alternative to using the Kudu APIs
to build a custom Kudu application. In addition, you can use JDBC or ODBC
to connect existing or new applications written in any language, framework,
or business intelligence tool to your Kudu data, using Impala as the broker.
This integration relies on features that released versions of Impala do not
have yet, as of Impala 2.3, which is expected to ship in CDH 5.5. In the
interim, you need to install a fork of Impala, which this document will
refer to as *Impala_Kudu*.
I have CDH 5.7 installed, does it contain the necessary changes for Impala
or do I still need to download impala-kudu.
Also, do you have any example on how to use c++ api?
Thanks
Roberta

Thanks that worked.
When I read the documentation, I got the impression that the URL was
required. The documentation just stated: the list of Kudu masters Impala
should communicate with.

Also, the default master RPC port is 7051, so you probably want to be using
that. 8051 is the http port, which is not suitable. Per the docs:
CREATE TABLE my_first_table ( id BIGINT, name STRING ) DISTRIBUTE BY HASH
(id) INTO 16 BUCKETS TBLPROPERTIES( 'storage_handler' =
'com.cloudera.kudu.hive.KuduStorageHandler', 'kudu.table_name' =
'my_first_table', 'kudu.master_addresses' = 'kudu-master.example.com:7051',
'kudu.key_columns' = 'id' );

So it should be:

Not the http url you currently have.

Hi Roberta
The master address in the create table statement should be in the format:
host:port
So it should be:
...
'kudu.master_addresses' = '<my_node_ip>:8051',
...
Not the http url you currently have.

You need to only specify the address and RPC port for your master, not the
web UI's URL. It should be 'kudu.master_addresses' = '<my node>:7051'
Where was it specified with the http URL?

RE: Kudu installation
Posted by Roberta Marton <ro...@esgyn.com>.
Thanks! I will check out the examples.
I have installed both Kudu and Impala-kudu and am trying to create a table
though Impala.
I verified that Impala-kudu is setup by running the select statement
suggested on the installation page.
When I try to create a table, it is complaining that it can't find my
master.
ERROR:
ImpalaRuntimeException: Error creating Kudu table
CAUSED BY: NonRecoverableException: Couldn't find a valid master in
([http://<master host>:8051/masters]), exceptions:
[org.kududb.client.NonRecoverableException: Couldn't resolve this master's
address [http://<master host>:8051/masters]]
I can go to http://<master host>:8051/masters and see master details. I am
missing something in the configuration?
Roberta

Hi Roberta,
For the foreseeable future you still need to download the special Impala
Kudu.
As for C++ API examples, check out this:
