Unable to launch hive

Question

I am not able to launch Hive while following the getting started procedure

Here is the error:

$ ./hive
SLF4J: Class path contains multiple SLF4J bindings.

I believe the problem is coming from the java version, based on other SO questions. But they did not help me.

When I run java -version, I get:

openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3, mixed mode, sharing)

However, when I get my $JAVA_HOME variable, it is correctly set to java 1.8:

$ echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-amd64

BUT, when I use the alternative command to select my java version, I get the following result:

$ sudo update-alternatives --config java
[sudo] password for hadoopuser: 
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1111      auto mode
  1            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1111      manual mode
* 2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode

Press <enter> to keep the current choice[*], or type selection number: 2

What am I doing wrong?

Edit 1 : Similar error when running ./beeline -u jdbc:hive2://

Answer 1

For exactly same problem with Hadoop version 3.3.5 and Hive 3.1.3. on Ubuntu 22.04, I have to install JDK with below command

sudo apt install openjdk-8-jdk

and Then set JAVA_HOME as follows

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/
export PATH="/usr/lib/jvm/java-8-openjdk-amd64/bin:$PATH"

Below option does not fix the issue for me

export PATH="/usr/lib/jvm/java-1.8.0-openjdk-amd64/bin:$PATH"

Answer 2

It might be that the binaries for Java 11 are still first in your PATH. Check if the bin folder for Java 11 is appearing first with echo $PATH.

If that's the case, a quick fix might just be to prepend the path to the Java 8 bin folder to your .bashrc file. Appending something like this might help:

export PATH="/usr/lib/jvm/java-1.8.0-openjdk-amd64/bin:$PATH"

Then java -version should show the right one.
