Comment 2 for bug 1769323

Kashif,
can you let us know the java versions u have in the system. Make sure the build versions of the java also match. we have tested with OSD 10 as well and Kafka comes up fine. Here is a list of command and let us know the difference u observe. The commands have to be tried on contrailanalyticsdatabase container.

1) /usr/sbin/alternatives --config java
2) rpm -qa | grep kafka

Expected output:
root@overcloud-contrailanalyticsdatabase-0 heat-admin]# /usr/sbin/alternatives --config java

There are 2 programs which provide ‘java’.

 Selection Command

*+ 1 java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64/jre/bin/java)
  2 java-1.7.0-openjdk.x86_64 (/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.181-2.6.14.8.el7_5.x86_64/jre/bin/java)
