Executing logstash in command line worked successfully but putting the same command with the JAVA\_HOME & PATH variables set & exported in a shell script doesnt work. While running the shell script, logstash comes to the point showing the below, then it hangs/goes into an idefinite loop (on seeing the --debug output);
**Settings: Default pipeline workers: 16**
**Logstash startup completed**
With the --debug and -v option in the logstash command, it repeats the below message continuously;
\*\*Flushing buffer at interval \*\*
Why does it hang or go into indefinite loop while executing the same in a shell script ?
Note : ConfigTest is OK in both command line and shell script.
**Executing Logstash in Command Line in RHEL 5.8**
$ JAVA\_HOME=../java/jdk1.8.0\_77/bin
$ export PATH=$JAVA\_HOME:$PATH
$ ../logstash-2.2.2/bin/logstash -f \_config\_file \< \_data\_file

What does your script look like?
Why aren't you just using the RPM?

Hi Mark,
Thank you for your response;
Script looks like the below;
> #!/usr/bin/sh
> JAVA\_HOME=../java/jdk1.8.0\_77/bin
> export PATH=$JAVA\_HOME:$PATH
> CONFIGFILE=configFilePath
> DATAFILE=dataFilePath
> ../logstash-2.2.2/bin/logstash --configtest -f _CONFIGFILE_ \< _DATAFILE_
> sleep 10
> ../logstash-2.2.2/bin/logstash -f _CONFIGFILE_ \< _DATAFILE_
I downloaded the tar.gz file for the Linux O/S which I untarred as logstash-2.2.2, and using logstash as above. I'll try the RPM as well
Same result with RPM as well. logstash command hangs and goes into indefinite loop in debug.
