I am using Hive 2.1.0.
as per HPL/sql documentation HPL/SQL is included to Apache Hive since version 2.0.
Is there any additional configuration changes is required to enable hpl/sql support in hive.

We can't run HPL/SQL query directly from Hive Cli. we should use either
1. hplsql -e 'query' or 2. hplsql -e sql/hql file.
For Example-
hplsql -e 'dbms_output.put_line(`this is hplsql`)';
or
hplsql -e 'PRINT `this is hplsql`';

Write function in HPL/SQL, register it in hive and Use it.

Apache hive beeline error: JAVA Error: A JNI error has occurred, please check your installation and try again

This is what the beeline.cmd command looks like.
Hadoop is running smoothly including hdfs and yarn.
I am on Java 8.
What could be the problem?
I also received the same error. Then when i checked the file "beeline.cmd", i saw it needs hive-jdbc--standalone.jar**. So Downloading that and placing it in C:\Users-----\apache-hive-3.1.2-bin\lib solved the issue.

Problem invoking WLST - java.lang.RuntimeException: error in finding weblogic.Home

I am getting this error while trying to run the following WLST script :
"Problem invoking WLST - java.lang.RuntimeException: error in finding weblogic.Home"
However I have run the setWLSEnv.sh before running the script.
This problem has been solved by using the following argument with garbage collection script:
/opt/SP/oracle/product/fmw/java/bin/java -cp /opt/SP/oracle/product/fmw/wlserver_10.3/server/lib/weblogic.jar weblogic.WLST /opt/SP/oracle/home/scripts/runGC.py
Note: /opt/SP/oracle/product is the oracle middleware installation directory.

Unable to initialize hive with Derby from Brew install

It had been my understanding that Derby creates file(s) in the current directory. But there are none there.
So I had tried to do the hive initialization using Derby: but .. it seems there is a derby database already.

So .. where is it?
Update I have reinstalled hive from scratch using
brew reinstall hive
And the same error occurs.
Another update Given the new direction of this error it now is answered by within another question:
An answer to a non-os/x - but similar otherwise - question was found that can serve here:
https://stackoverflow.com/a/40017753/1056563
I installed hive with HomeBrew(MacOS) at /usr/local/Cellar/hive and afer running schematool -dbType derby -initSchema I get the following error message:
Starting metastore schema initialization to 2.0.0 Initialization script hive-schema-2.0.0.derby.sql Error: FUNCTION 'NUCLEUS_ASCII' already exists. (state=X0Y68,code=30000) org.apache.hadoop.hive.metastore.HiveMetaException: Schema initialization FAILED! Metastore state would be inconsistent !!
However, I can't find either metastore_db or metastore_db.tmp folder under install path, so I tried:
find /usr/ -name hive-schema-2.0.0.derby.sql
vi /usr/local/Cellar/hive/2.0.1/libexec/scripts/metastore/upgrade/derby/hive-schema-2.0.0.derby.sql
comment the 'NUCLEUS_ASCII' function and 'NUCLEUS_MATCHES' function
rerun schematool -dbType derby -initSchema, then everything goes well!
Homebrew installs Hive (version 2.3.1) unconfigured. The default settings are to use in-process Derby database (Hive already includes the required lib).
The only thing you have to do (immediatelly after brew install hive) is to initialize the database:
schematool -initSchema -dbType derby
and then you can run hive, and it will work. However, if you tried to run hive before initializing the database, Hive will actually semi-create an incomplete database and will fail to work:
show tables;
FAILED: SemanticException org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
Since the database is semi-created, schematool will now fail as well:
Error: FUNCTION 'NUCLEUS_ASCII' already exists. (state=X0Y68,code=30000)
org.apache.hadoop.hive.metastore.HiveMetaException: Schema initialization FAILED! Metastore state would be inconsistent !!
To fix that, you will have to delete the database:
rm -Rf metastore_db
and run the initilization command again.
Noticed that I deleted the metastore_db from current directory? This is another problem: Hive is configured to create and use the Derby database in current working dir. This is because it has the following default value for ‘javax.jdo.option.ConnectionURL’:
jdbc:derby:;databaseName=metastore_db;create=true
To fix that, create file /usr/local/opt/hive/libexec/conf/hive-site.xml as
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:derby:/usr/local/var/hive/metastore_db;create=true</value>
</property>
</configuration>
and recreate the database like before. Now the database is in /usr/local/var/hive, so in case you again accidentally ran hive before initializing the DB, delete it with:
rm -Rf /usr/local/var/hive
You might have to look at the hive configuration file. That should tell you where it is being initialized.

And according to other threads, its datanode issue, but all of my datanodes are up and running.
I think the problem maybe lack of write permissions on /tmp directory.
Try hadoop dfs -chmod g+w /tmp ?
