Beeline connection Error

priyanka1_munja — Fri, 16 Sep 2022 10:40:01 GMT

I am new in Hadoop. I have cloudera (pseudo mode) in my system and I have downloaded it in Virtual Box. I am unable to connect to Beeline. The error which I am getting:-

[cloudera@quickstart ~]$ beeline

2016-09-18 20:10:18,995 WARN [main] mapreduce.TableMapReduceUtil: The hbase-prefix-tree module jar containing PrefixTreeCodec is not present. Continuing without it. Beeline version 1.1.0-cdh5.7.0 by Apache Hive

beeline> show databases;

No current connection

beeline> !connect jdbc:hive2//hostname:10000 scan complete in 5ms scan complete in 6272ms No known driver to handle "jdbc:hive2//hostname:10000"

beeline>

In this, I think I need to download the jdbc driver but while using sqoop with hive, I am able to use jdbc connection. Moreover can u please tell how I can check whether my server2 is running or not. I am working in VB cloudera, so i don't know how to download the things

1. I assume you are using my sql

Check if MySQL connector jar file accessible to Hive

2. Check Meta store status

sudo service hive-metastore status

3. ps -ef | grep RunJar

4. Check Hive Server2 status

sudo service hive-server2 status

5. Finally check your hive-site.xml to see if you have missed the driver name
