-----------------------------------

             Summary: JVM crash with dynamic netty-tcnative wrapper to openSSL 
on some OS
                 Key: FLINK-13172
                 URL: https://issues.apache.org/jira/browse/FLINK-13172
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Network, Tests
    Affects Versions: 1.9.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber


The dynamically-linked wrapper library in 
{{flink-shaded-netty-tcnative-dynamic}} may not work on all systems, depending 
on how the system-provided openSSL library is built.
As a result, when trying to run Flink with {{security.ssl.provider: OPENSSL}} 
or running a test based on {{SSLUtilsTest}} (which checks for openSSL 
availability), the JVM will crash, e.g. with
- on SUSE-based systems:
{code}
/usr/lib64/jvm/java-openjdk/bin/java: relocation error: 
/tmp/liborg_apache_flink_shaded_netty4_netty_tcnative_linux_x86_644115489043239307863.so:
 symbol TLSv1_2_server_method version OPENSSL_1.0.1 not defined in file 
libssl.so.1.0.0 with link time reference
{code}
- on Arch Linux:
{code}
/usr/lib/jvm/default/bin/java: relocation error: 
/tmp/liborg_apache_flink_shaded_netty4_netty_tcnative_linux_x86_648476498532937980008.so:
 symbol SSLv3_method version OPENSSL_1.0.0 not defined in file libssl.so.1.0.0 
with link time reference
{code}

Possible solutions:
# build your own OS-dependent dynamically-linked {{netty-tcnative}} library and 
shade it in your own build of {{flink-shaded-netty-tcnative-dynamic}}, or
# use {{flink-shaded-netty-tcnative-static}}:
{code}
git clone https://github.com/apache/flink-shaded.git
cd flink-shaded
mvn clean package -Pinclude-netty-tcnative-static -pl 
flink-shaded-netty-tcnative-static
{code}
# get your OS-dependent build into netty-tcnative as a special branch similar 
to what they currently do with Fedora-based systems
