-----------------------------------
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.gitcd 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
