How to setup knox for Hive LLAP

I have added below block in knox topology

<service>
<role>HIVE2</role>
<url>http://FQDN_LLAP_SERVER:10501/cliservice</url>
</service>

Also, created the directory in "$KNOX_HOME/data/services/hive2" with service.xml and rewrite.xml files.

Also enabled below properties in Hiveserver2-Interactive-site.xml file,

hive.server2.thrift.http.path=cliservice
hive.server2.transport.mode=http

service.xml

<service role="HIVE2" name="hive2" version="0.13.0">
    <routes>
        <route path="/hive2"/>
    </routes>
    <dispatch classname="org.apache.hadoop.gateway.hive.HiveDispatch" ha-classname="org.apache.hadoop.gateway.hive.HiveHaDispatch"/>
</service>

rewrite.xml

<rules>
    <rule dir="IN" name="HIVE2/hive2/inbound" pattern="*://*:*/**/hive2">
        <rewrite template="{$serviceUrl[HIVE2]}"/>
    </rule>
</rules>

Getting below error in knox while accessing this path from ODBC driver,

hadoop.gateway Failed to match path /hive2

1) Edit the Advanced topology of your KNOX service to add LLAP service

<service>
<role>LLAP</role>
<url>http://<LLAP server host>:<HTTP PORT NUMBER>/{{hive_http_path}}</url>
</service>

2) Go to the below location in your KNOX server machine:-
/usr/hdp/<HDP VERSION>/knox/data/services

3) Copy the hive directory present in the location and rename it as llap

4) Edit the services.xml and rewrite.xml as below:-

servcies.xml
------------
<service role="LLAP" name="llap" version="0.13.0">
<routes>
<route path="/llap"/>
</routes>
<dispatch classname="org.apache.hadoop.gateway.hive.HiveDispatch" ha-classname="org.apache.hadoop.gateway.hive.HiveHaDispatch"/>
</service>

<rules>
<rule dir="IN" name="LLAP/llap/inbound" pattern="*://*:*/**/llap">
<rewrite template="{$serviceUrl[LLAP]}"/>
</rule>
</rules>

Use the http path as 'gateway/default/llap' while connecting to LLAP via KNOX.

Hi,

We use your configuration, but don't work.

We don't use doAS (https://community.hortonworks.com/questions/107790/hive-interactive-and-hiveserver2enabledoas.html).

How would be create a connection string? We use this:

jdbc:hive2://<<host>>:8443/;ssl=true;transportMode=http;httpPath=gateway/default/llap;sslTrustStore=knox.jks;trustStorePassword=xxxxxx

Could you help us and any idea where is the problem?

Hi @Radoslaw Klewin

Hive LLAP does not currently support hive.server2.enable.doAs=true, hence the error I suspect.
