Internal error on "CREATE VIRTUAL SCHEMA"

Steps:

run exasol in docker https://github.com/EXASOL/docker-db#manually-creating-an-exasol-container
deploy adapter according to https://github.com/EXASOL/virtual-schemas/blob/master/jdbc-adapter/doc/deploy-adapter.md see datagrip/exasol:latest image in docker hub https://hub.docker.com/r/datagrip/exasol/~/dockerfile/
execute
```
CREATE SCHEMA adapter;
```

CREATE JAVA ADAPTER SCRIPT adapter.jdbc_adapter AS

%scriptclass com.exasol.adapter.jdbc.JdbcAdapter;

%jar /buckets/bucketfs/bfsdefault/default/virtualschema-jdbc-adapter-dist-0.0.1-SNAPSHOT.jar;

* execute

CREATE CONNECTION exasol_conn TO 'jdbc:exa:192.168.99.100:8899' USER 'sys' IDENTIFIED BY 'exasol';

CREATE VIRTUAL SCHEMA virtual_exasol USING adapter.jdbc_adapter WITH SQL_DIALECT = 'EXASOL' CONNECTION_NAME = 'EXASOL_CONN' SCHEMA_NAME = 'default';



Result:
Error fired:
[22002] VM error: Internal error: VM crashed (Session: 1576534527788307527)

UPD: I tried to create virtual schema using EXAplus application and I received the same error

| 14:24:12.603 | [22002] VM error: Internal error: VM crashed (Session: 1576611240647135888)

This could be a memory related issue (too little memory granted for the JVM), but we have to look in the logs.

Could you attach the logs here? The issue https://github.com/EXASOL/docker-db/issues/5 has some comments at the end about how to obtain the logs in Docker (I cannot test it right now). Let us know if this doesn't work for you.

You could also do some tests with tuning the Xmx and Xms parameters, e.g. set lower values, and see if this helps. Just specify jvmoption as follows.

CREATE JAVA ADAPTER SCRIPT adapter.jdbc_adapter AS
%jvmoption -Xms64m -Xmx128m;

Hi, I tried to use jmvoptions tuning with values you provided. The same error. [2017-08-29 18:10:01] [22002] VM error: Internal error: VM crashed (Session: 1577078562553184554)

Thanks for trying out jvmoptions. However, the docker logs were not sufficient (my comment was a bit unclear about this), instead we need the full content of the logs directory. You can obtain this as follows: If you followed the steps described at https://github.com/exasol/docker-db with --root ~/MyCluster/, then the logs will be stored in ~/MyCluster/n11/logs/db/DB1. There should be many files, recently updated. Please send an archive with this folder content.

@andrehacker Logs you asked: l.tar.gz Thank you.

@tjlee I can not reproduce your problem, if I call it, than I get following:

SQL_EXA> CREATE VIRTUAL SCHEMA virtual_exasol USING adapter.jdbc_adapter WITH SQL_DIALECT = 'EXASOL' CONNECTION_NAME = 'EXASOL_CONN' SCHEMA_NAME = 'TEST';

And it is, because the bucket is not /buckets/bucketfs/bfsdefalt/default but /buckets/bfsdefault/default, with correct path it looks like following for me:

SQL_EXA> CREATE VIRTUAL SCHEMA virtual_exasol USING adapter.jdbc_adapter WITH SQL_DIALECT = 'EXASOL' CONNECTION_NAME = 'EXASOL_CONN' SCHEMA_NAME = 'TEST';

To look, what you have, you can use this handy script:

SQL_EXA> CREATE PYTHON SCALAR SCRIPT ls(p VARCHAR(10000)) EMITS (n VARCHAR(10000)) as
1  > def run(ctx):
2  >   import os
3  >   for x in os.listdir(ctx.p):
4  >     ctx.emit(os.path.join(ctx.p, x))
5  > /

Then you could use it like follows:

SQL_EXA> select ls('/buckets/bfsdefault/default');
EXA: select ls('/buckets/bfsdefault/default');

N

But I do not get any crash, do you have the latest exasol/docker-db image? (my has ID 716a0d81cf30)

@ooke Hi, Our custom image is based on exasol/docker-db:latest

FROM exasol/docker-db:latest
ADD "virtualschema-jdbc-adapter-dist-0.0.1-SNAPSHOT.jar" /
ADD entrypoint.sh /

ENTRYPOINT ["/entrypoint.sh"]

You can find files here: https://github.com/DataGrip/docker-env/tree/master/exasol

We found out, that we can't execute java and python script (only lua). When we try to execute ls we've got [22002] VM error: Internal error: VM crashed (Session: 1577701465689038336) Do we need to enable java & python support somehow?

@tjlee Hi,

which Linux kernel do you use? Can you please paste the output of uname -a command?

I can not reproduce your problem, if I build the docker image from your Dockerfile it still works. Could maybe you try to reproduce this output:

@tjlee sorry, I do not see any problem. Could you please send me your public SSH key to ok@exasol.com, I will create an AWS instance and give you access to it and we will try to reproduce your problem there together, is it an acceptable plan for you?

@ooke Hi, You can close the ticket. Possibly, I found the problem. I use boot-to-docker as OS to host EXASOL. I can't reproduce the problem on Ubuntu. Thank you.

@ooke we face the issue again. Success rate is about 90% for the test and it fails with the same error java.sql.SQLException: VM error: Internal error: VM crashed (Session: 1788406532139843584)
