Please help to resolve this error.

@Amit Dass Can you please check Hive Metastore logs for any errors/exceptions. Assuming you are using mysql as Metadata. Further Can you check if mysql is running and you can ping/telnet to mysql with the setting in the hive-site.xml and connect mysql with username/pwd provided in hive-site.xml

Expert Contributor

Yes user name and passwords are there at <value> tag of : <name>javax.jdo.option.ConnectionUserName</name> , <name>javax.jdo.option.ConnectionPassword</name> . Can you please elloborate the steps to check whether mysql is working or not .

Expert Contributor

Have you checked hivemetastore.log, did you find any errors ?

@Amit Dass - Looks like your HiveMetastore process is not running, I can see connection refused from the logs

Could not connect to meta store using any of the URIs provided. Most recent failure: org.apache.thrift.transport.TTransportException: Connection refused at

Or there might be some connection issues with hive client and hive metastore machine.

Can you please check connectivity as well ?

Expert Contributor

@Kuldeep Kulkarni : Can you please brief that how should I check connectivity?

Super Guru

@Amit Dass

From hive client (from where you are running hive command) check if you are able to run below command

telnet <hive-metastore-hostname/ip-address> 9083

On metastore:

try running below command to check is metstore process is running

ps aux|grep HiveMetaStore

try running below command to ensure that metastore process is listening on 9038

root@sandbox ~]# netstat -tulpn|grep 9083
tcp        0      0      *                   LISTEN      2115/java
[root@sandbox ~]#

Expert Contributor

@Kuldeep Kulkarni : Getting connection refused as below also why we use port 9038

telnet xx.xx.xx.xx 9038

Trying xx.xx.xx.xx... telnet: connect to address xx.xx.xx.xx: Connection refused

Super Guru

Sorry I have corrected port number, please try the steps given above and let me know how it goes

@Amit Dass - I'm assuming you have installed cluster with Ambari, Please go to the ambari server UI and check on which host hive metostore is installed, you can go to the hive services and click on metastore service to check the same.

If Ambari shows metastore as down then you need to start it.

Expert Contributor

@Kuldeep Kulkarni :No I am not using Ambari

I am using distributed system which has one namenode and two datanode . This for POC purpose only .

This is simple unix machine which had hadoop , hive ,hbase installed. Please guide me accordingly.

@Amit Dass

Can you please follow below steps and share the result?.

1. Find out the node which hosting hive metastore service, you can use ambari to figure out the ip/hostname for that node.

2. ssh root login to that hive metastore node and execute below commands.

bash# ps -aef|grep -i org.apache.hadoop.hive.metastore.HiveMetaStore

bash# lsof -i:9083

3. From some other node try connecting hivemetastore port using telnet.

bash# telnet <hivemeta server> 9083

If 9083 port is not occupied and ps command doesn't show any metastore process then please try to restart the hivemestore service from ambari UI and perform same check again.

@Jitendra Yadav : Thanks , I am using distributed system which has one namenode and two datanode . This for POC purpose only . Can you please elaborate more on this .

I logged in Namenode assume : xx.xx.xx.xx

Hadoop hdfs commands working fine.

But when I try to enter into hive shell it throwing error.

1. As hive installed in Namenode so we had IP of namenode.

2. ps -aef|grep -i org.apache.hadoop.hive.metastore.HiveMetaStore

o/p : hadoop 15097 13478 0 16:21 pts/2 00:00:00 grep -i org.apache.hadoop.hive.metastore.HiveMetaStore

lsof -i:9083

o/p : Did not get any output for the same

3. Getting connection refused .. telnet < Namenode IP> 9083

This is simple unix machine which had hadoop , hive ,hbase installed. Please guide me on this.

@Amit Dass

So looks like your hive metastore service is not running, Would you please try to start metastore service from ambari UI? please see attachement.screen-shot-2016-04-20-at-23103-pm.png

@Amit Dass

Please below command to start the hivemetastore..

nohup /usr/hdp/current/hive-metastore/bin/hive --service metastore>/var/log/hive/hive.out 2>/var/log/hive/hive.log &

@Amit Dass

Hi Amit, if you run the below command from one terminal then metastore process will run into background and even if you close the terminal it shouldn't terminate the process. So please use it with nohup.

nohup /usr/hdp/current/hive-metastore/bin/hive --service metastore >/var/log/hive/hive.out 2>/var/log/hive/hive.log &

@Amit Dass

Please accept my answer if this is now resolved after my suggestion.
