How did you install Elasticsearch?
What user are you running as?

hi,
i installed with user zebra.
i made my own Installation Zip-File.
in ELK 6.2.4 it was installed correctly

There is some issue between the way you installed Elasticsearch, the user you installed it as and the user you are running it as.

You have a permissions problem running the /global/zebra/elkstack/oem/elasticsearch-6.3.1/modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/controller process.

The 6.3.1 zip file has the correct permissions for that file:

-rwxr-xr-x  2.0 unx    84352 b-    31823 defN 18-Jun-29 22:04 elasticsearch-6.3.1/modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/controller

So it appears that your installation process has failed to set the correct permissions.

in ELK 6.2.4 it was installed correctly

In 6.2.4 X-Pack was a plugin which was installed for you by elasticsearch-plugin, so the process you used to install Elasticsearch would not have affected the permissions on the ML controller.

Thanks.
in ELK 6.2.4 i don't use xpack.

Is it possible to install ELK 6.3.x without xpack.

i use search-guard for security

Hi, I'm trying to impement custom StemFilter, that uses external program as stemmer. I got the same error.

I've implemented simple TokenFilter, that calls external program like this

        SecurityManager sm = System.getSecurityManager();
    if (sm != null) {
        sm.checkPermission(new SpecialPermission());
    }

    mystemProcess = AccessController.doPrivileged((PrivilegedAction<Process>) () -> {
        ProcessBuilder pb = new ProcessBuilder("/usr/local/bin/mystem", "-ign", "--format", "json");
        try {
            return pb.start();
        } catch (IOException e) {
            LOG.error(e);
            return  null;
        }
    });

And I got the same error:

Caused by: java.io.IOException: error=13, Permission denied
    at java.lang.UNIXProcess.forkAndExec(Native Method) ~[?:1.8.0_161]
    at java.lang.UNIXProcess.<init>(UNIXProcess.java:247) ~[?:1.8.0_161]
    at java.lang.ProcessImpl.start(ProcessImpl.java:134) ~[?:1.8.0_161]
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029) ~[?:1.8.0_161]
    ... 24 more

Could you help me?

P.S. File permissions are set correctly:

user@server:/usr/local/bin$ ls -la | grep mystem
-rwxrwxrwx  1 root staff 21135640 Aug 16 14:38 mystem
