Presto not able to connect to hive: Failed connecting to Hive metastore:

[#1]

I am trying to connect to hive metastore to my HDP sandbox. However it's throwing following error.

Hive Catalogonnector.name=hive-hadoop2
hive.metastore.uri=thrift://sandbox-hdp.hortonworks.com:9083
hive.metastore.authentication.type=NONE

Error:

Query 20180810_005352_00000_umgac failed: Failed connecting to Hive metastore: [sandbox-hdp.hortonworks.com:9083]

I tried using following values for hive.metastore.uri however I am gettting the same error.

• thrift://localhost:9083
• thrift://127.0.0.1:9083
• thrift://<IP of docker container>:9083
• thrift://<IP of local machine>:9083

Is your metastore up and running? if it is up and running in the in the same machine you shouldn't be seeing this error.

Do post the complete stacktrace.

@Sandeep Nemuri

how do i check if metastore is up and running from my local machine. I logged into docker container and I can see I am able to telnet into the 9083 port. However if I try to do that from my local machine, it doesn't work.

The one thing I realized is the port is not exposed in docker image or mentioned in webpage anywhere.

https://hortonworks.com/tutorial/hortonworks-sandbox-guide/section/3/

I exposed the port and restarted the docker container however, I am still not able to connect to that port using telnet from my local machine or from presto server ( which also on my local machine).

I don't think you will be able to connect form the presto outside of sandbox. One easy solution i can think of is to install presto service within sandbox docker.

I found the solution, so posting here.

The problem I was having is I was just stopping the docker container after making change in the command I was using to start the HDP image, didn't realize need to remove container as well.

Following command helped.

Save docker Work

docker commit <hdp_container_id> <hdp_container_id>

Stop and Remove docker.

docker stop <hdp_container_id>
docker rm <hdp_container_id>

Open 9083 port (hive metastore) by modifying start-sandbox-hdp-standalone_2-6-4.sh

#!/bin/bash
echo "Waiting for docker daemon to start up:"
until docker ps 2>&1| grep STATUS>/dev/null; do  sleep 1; done;  >/dev/null
docker ps -a | grep sandbox-hdp
if [ $? -eq 0 ]; then
 docker start sandbox-hdp
else
docker pull hortonworks/sandbox-hdp-standalone:2.6.4
docker run --name sandbox-hdp --hostname "sandbox-hdp.hortonworks.com" --privileged -d \
-p 9083:9083 \ 
-

Start Docker

./start-sandbox-hdp-standalone_2-6-4.sh
