Manually deploying Logstash on Power

For IBM Spectrum LSF Suite for HPC 10.2 Fix Pack 10 and later, deploying Logstash on Power systems requires manual steps.

Procedure

Download Logstash 7.2.1 tar.gz package: https://www.elastic.co/cn/downloads/past-releases/logstash-7-2-1.
Extract the package to a directory, for example, /opt:
```
tar zxvf logstash-7.2.1.tar.gz -C /opt
```
Download OpenJDK8U-jre_ppc64le_linux_hotspot_8u202b08.tar.gz: https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/tag/jdk8u202-b08

Extract OpenJDK8U to a directory, for example, /opt

tar zxvf OpenJDK8U-jre_ppc64le_linux_hotspot_8u202b08.tar.gz -C /opt

Set the JAVA_HOME environment variable.
```
export JAVA_HOME=/opt/jdk8u202-b08-jre
```

Fix the compatibility issue with the jruby-complete-9.2.7.0.jar platform:

cd /opt/logstash-7.2.1/logstash-core/lib/jars
mkdir jruby_repack
unzip jruby-complete-9.2.7.0.jar -d ./jruby_repack
cd /opt/logstash-7.2.1/logstash-core/lib/jars/jruby_repack/META-INF/jruby.home/lib/ruby/stdlib/ffi/platform/powerpc64le-linux/
cp types.conf platform.conf
cd /opt/logstash-7.2.1/logstash-core/lib/jars/jruby_repack
zip -r jruby-complete-9.2.7.0.jar *
mv -f jruby-complete-9.2.7.0.jar ../

After installing IBM Spectrum LSF Suite for HPC restart logstash.
```
/opt/logstash-7.2.1/bin/logstash
```
