Does Knox’s Hive service configuration support the overloaded URLs used in the HiveServer2 + ZK HA approach?

wfloyd — Fri, 08 Apr 2016 03:30:08 GMT

Does Knox’s Hive service configuration support the overloaded URLs used in the HiveServer2 + ZK HA approach? For example would this be a supportable Knox configuration:

<service>    
<role>HIVE</role>
<url>http://zk1.customer.com:2181,zk2.customer.com:2181,zk2.customer.com:2181/cliservice</url>
</service>

Not sure if the ZK URL can be passed through Knox?

See the Apache docs here for HiveServer2 HA support:

Hi @Wes Floyd, support for HS2 HA Zookeeper discovery is also available in Knox-0.7, but the version of Knox packaged in the latest HDP-2.4 is still 0.6, and so it's not yet availalbe in HDP. You can consider to install it yourself.

Hi @Predrag Minovic do you know when will Knox-0.7 or better be included with HDP-2.4? Thanks, Jason.

For HDP 2.5+ the answer is yes.
