Hive CLI Error: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
Hi All, I'm new to Hive and did this tutorial: https://cwiki.apache.org/confluence/display/Hive/GettingStarted After the "Running Hive CLI" step I've decided to run the "show tables;" command and got this error: FAILED: HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient Do you have any idea how to solve this? I've tried implementing solutions listed in the top 10 search results for this error to no avail. Should I try the next 10 results? Thanks, Val

You might want to check the HiveServer2 log which should have the complete exception trace to understand why it is not able to create a MetastoreClient.

RES: Error "Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient"
Hi Fabricio, did you solve this ? Looks that your Hive is not accessing the MetaStore database... Did you try to connect on Derby directly ? or this Machine and port are accessible ?

Re: Error "Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient"
Hi, I recommend you try using HiveServer2 and beeline as explained here: https://cwiki.apache.org/confluence/display/Hive/GettingStarted#GettingStarted-RunningHiveServer2andBeeline.1 In particular, please make sure you have run "bin/schematool -dbType derby -initSchema" and that it returned successfully, as this command is required to initialize your derby backend. Hope this helps, Furcy 2017-11-21 1:37 GMT+01:00 Fabricio Pedroso Jorge : > Hi all, > > Hadoop verrsion...: 2.6.0 (Oracle Linux 7) > Hive version.: 2.3.2 > > I am quite a newbie at the Hive world, and because of that, i am getting > the following error averytime i try to execute a command at the hive CLI: > > > *hive> show tables;FAILED: SemanticException > org.apache.hadoop.hive.ql.metadata.HiveException: > java.lang.RuntimeException: Unable to instantiate > org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient* > > My metastore is at $DERBY_HOME/data and my hive-site.xml has the following > configuration, regarding the Derby connection: > > > > > > > > *javax.jdo.option.ConnectionURL > jdbc:derby://h-master:1527/metastore_db;create=true > JDBC connect string for a JDBC metastore.
