Hi Team, I have done my setup of using Logstash, elasticsearch and kibana for my systems performance data on rhel using latest 6.x version. It all works fine. Now I need to move this setup on Linux(rhel) on system z (mainframe) I started first with elasticsearch for which I downloaded the tar files and unzipped it. When executing elasticsearch command from bin folder, I get error as below - Exception in thread "main" org.elasticsearch.bootstrap.BootstrapException: java.security.spec.InvalidKeySpecException: Could not generate secret key Likely root cause: java.lang.RuntimeException: Error deriving PBKDF2 keys at com.ibm.crypto.provider.PBKDF2KeyImpl.a(Unknown Source) at com.ibm.crypto.provider.PBKDF2KeyImpl.(Unknown Source) at com.ibm.crypto.provider.bn.engineGenerateSecret(Unknown Source) at javax.crypto.SecretKeyFactory.generateSecret(Unknown Source) at org.elasticsearch.common.settings.KeyStoreWrapper.createCipher(KeyStoreWrapper.java:289) at org.elasticsearch.common.settings.KeyStoreWrapper.encrypt(KeyStoreWrapper.java:361) at org.elasticsearch.common.settings.KeyStoreWrapper.save(KeyStoreWrapper.java:473) at org.elasticsearch.bootstrap.Bootstrap.loadSecureSettings(Bootstrap.java:234) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:291) at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:136) at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:127) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.Command.main(Command.java:90) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:93) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:86) Refer to the log for complete error details. What am i missing here ? ---

I think that your OS or your JVM is not supported. See [https://www.elastic.co/support/matrix](https://www.elastic.co/support/matrix) ---

I was using [https://github.com/linux-on-ibm-z/docs/wiki/Building-Elasticsearch](https://github.com/linux-on-ibm-z/docs/wiki/Building-Elasticsearch) as reference and seems its supported. ---

You are trying to run on the IBM JDK which is not supported by Elasticsearch. ---
