java.lang.AssertionError - accumulo examples

I cloned the accumulo examples, and followed the instructions in the READMe
file:

https://github.com/apache/accumulo-examples/blob/main/README.md

but when I run  ./bin/build I get an AssertionError;

I am not able to get rid of it,

I am using Java 11.



christine@centauri:~/accumulo-examples$ mvn --version |grep -i java  
Java version: 11.0.11, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-
amd64  
christine@centauri:~/accumulo-examples$ java -version  
openjdk version "11.0.11" 2021-04-20  
OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2.20.04)  
OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2.20.04, mixed mode,
sharing)







I am able to run accumulo 2.0.1 finally. Not sure what the problem was, but
after I ran bin/hdfs namenode -format

and accumulo init once again it works.



Thanks in advance for any help. I promise this is my last silly question. I
searched google and stackoverflow but i was not able to solve this,






Re: java.lang.AssertionError - accumulo examples

Posted by Christopher <ct...@apache.org>.
It looks like the examples were updated to work with 2.1.0-SNAPSHOT's
new Constraint SPI, which doesn't exist for 2.0.1. Try checking out
the 2.0 branch in the accumulo-examples, if you're trying to run them
with 2.0.

Thanks Mark and Christopher, yes the branch was the problem, it works now!

Are you running the examples against version 1.10.x or 2.x version of
Accumulo? The examples repo has been updated to run against the 2.x versions
of Accumulo. The 'main' branch is set up to run against the current 2.1.x
branch that is in development while the '2.0' branch should run against the
2.0.x version of Accumulo.

And I should mention,

I get the AssertionError when I remove the folder 'constraints' in

/accumulo-examples/src/main/java/org/apache/accumulo/examples



When I keep folder there, then I get this message:

I am not able to get rid of it,

I am using Java 11.

I am able to run accumulo 2.0.1 finally. Not sure what the problem was, but
after I ran bin/hdfs namenode -format

and accumulo init once again it works.



Thanks in advance for any help. I promise this is my last silly question. I
searched google and stackoverflow but i was not able to solve this,

Aw: java.lang.AssertionError - accumulo examples

Posted by Christine Buss <ch...@gmx.de>.

And I should mention,

I get the AssertionError when I remove the folder 'constraints' in

/accumulo-examples/src/main/java/org/apache/accumulo/examples



When I keep folder there, then I get this message:

Does that have anything to do with the Assertion Error?









**Gesendet:**  Donnerstag, 15. Juli 2021 um 17:48 Uhr  
**Von:**  "Christine Buss" <ch...@gmx.de>  
**An:**  user@accumulo.apache.org  
**Betreff:**  java.lang.AssertionError - accumulo examples

I cloned the accumulo examples, and followed the instructions in the READMe
file:

<https://github.com/apache/accumulo-examples/blob/main/README.md>

but when I run  ./bin/build I get an AssertionError;
