spark-class Could not find or load main class org.apache.hive.beeline.BeeLine

Hello to all,

 

I'm trying to execute a command

 

/opt/cloudera/parcels/CDH/lib/spark/bin/spark-beeline -u 'jdbc:hive2:<myserver>:10000' -f /root/testquery.sql

 

and get an error

 

Error: Could not find or load main class org.apache.hive.beeline.BeeLine

 

spark-beeline is a script (taken from spark repository with some path modifications):

 

set -o posix
export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera
# Figure out if SPARK_HOME is set
if [ -z "${SPARK_HOME}" ]; then
  source "$(dirname "$0")"/find-spark-home
fi
CLASS="org.apache.hive.beeline.BeeLine"
exec "/opt/cloudera/parcels/CDH/lib/spark/bin/spark-class" $CLASS "$@"

 

 

I think that I need to add a classpath to Hive Beeline (maybe

/opt/cloudera/parcels/CDH/lib/hive/lib/hive-beeline.jar). I tryed to add 

--driver-class-path /opt/cloudera/parcels/CDH/lib/hive/lib/hive-beeline.jar and 

--conf "spark.executor.extraClassPath=/opt/cloudera/parcels/CDH/lib/hive/lib/hive-beeline.jar" options to command without results.

 

What am I doing wrong?

Thanks!

After I copied all symlinks /opt/cloudera/parcels/CDH/lib/hive/lib/ to /opt/cloudera/parcels/CDH/lib/spark/jars/, the problem was resolved.

Update:

 

I created a symbolic link to hive-beeline.jar in /opt/cloudera/parcels/CDH/lib/spark/jars/.

Now I get this error:

 

Error: A JNI error has occurred, please check your installation and try again

I also tried to specify the jars path to /opt/cloudera/parcels/CDH/jars - with the same result.
