Pivotal HDB (commercial version of Apache Hawq) has been discontinued. You would need to build Apache Hawq from their open source repo http://github.com/apache/incubator-hawq. Here are the instructions for building Hawq https://cwiki.apache.org/confluence/display/HAWQ/Build+and+Install

@grabowski14 What kind of platform is your Hadoop cluster running under (e.g. OSX, Centos6, etc)? You must have PXF server running on all the data-nodes as well as on the name node. It is best if you use Ambari to install HAWQ and PXF as it guides you with the setup.

Please take a look at pxf-private.classpath to make sure the hive jars have the correct path. Also, take a look at pxf-service.log under tomcat where PXF is running. The above error is being returned from the PXF java server to C client.

I am running into the same issue. Any ideas?

ljain · ‎10-25-2017

Here are some sample entries from my pg_hba.conf for HAWQ master local all all ident host all all 127.0.0.1/28 trust host all gpadmin ::1/128 trust

It looks like something is running on port 51200 that is blocking PXFwebapp. You may try using: netstat -plan | grep 51200

Leonard, I was referring to your last message on Dec 20, where you mentioned that you were unable to initialize HAWQ 2.0.1 with HDP 2.4 VM. Let me try installing HAWQ with HDP 2.5 VM sometime this week.

ljain · ‎01-03-2017

Hi Leonard, I would need the URL that you used to download HDP 2.4 VM. Is your sandbox using docker or vagrant?

ljain · ‎12-15-2016

Pivotal HDB 2.1 does not delete the hawqmaster.py script. It includes a plugin that copies metainfo.xml onto the HDP 2.5 stack directory inside Ambari so that Ambari recognizes HDB 2.1 as part of the stack. I can take a look at your cluster if you deploy it to an AWS instance using the HDP 2.5 docker sandbox. One other option would be to uninstall SOLR before upgrading.

ljain · ‎12-14-2016

Hi Leonard, I checked both Docker as well as VirbualBox sandboxes for HDP 2.5 and they both contain hawqmaster.py I did not get a time to try the install of HDB 2.1 yet. The upgrade to Ambari 2.4.2 is independent of HDP install (looks like upgrade of SOLR component has a problem).

ljain · ‎12-10-2016

Hi Leonard, The installation that you have sounds like a stripped down version of Ambari. Please download Ambari 2.4.2 from Hortonworks (Ambari for Centos6) and install HDP 2.5 stack using Ambari. Please also post the URL for the tarball that you used for your current setup so we can investigate further.

ljain · ‎12-09-2016

Which version of Ambari are you using? The file hawqmaster.py is part of Ambari (not HDB 2.1)

ljain · ‎12-09-2016

Leonard, If Ambari is installed correctly then /var/lib/ambari-agent/cache/common-services/HAWQ/2.0.0/* should be present on each node. As part of bootstrapping the hosts in the cluster, Ambari-server copies the common-services directory and some other stuff to each of the hosts.

The following curl command gives the token (but uses the name node directly). $ curl -s --negotiate -u : "http://<active-namenode-hostname>:50070/webhdfs/v1/?op=GETDELEGATIONTOKEN" Is it possible to use dfs.nameservices property to get the token instead.

ljain · ‎01-04-2016

Thanks again! Here is what worked for me (using python 2.6.6). Still need to investigate how to run the test from ambari root directory. $ pip install discover $ export PYTHONPATH=~/git/ambari/ambari-common/src/test/python $ cd ~/git/ambari/ambari-server/src/test/python/stacks/2.3/common $ python -m discover -v Test that HAWQSTANDBY is not recommended on a single node cluster ... ok ... ---------------------------------------------------------------------- Ran 21 tests in 0.318s OK

Hi Artem, Thanks a lot for your input. I was looking to test stack advisor recommendations and validations. e.g. ambari/ambari-server/src/test/python/stacks/2.3/common/test_stack_advisor.py

ljain · ‎12-30-2015

e.g. mvn -Dtest=TestHDP23StackAdvisor test
