I checked with migration plugin and everything's ok. I upgraded with yum.
This is the message:
> Process: 7195 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -Des.pidfile=${PID\_DIR}/elasticsearch.pid -Des.default.path.home=${ES\_HOME} -Des.default.path.logs=${LOG\_DIR} -Des.default.path.data=${DATA\_DIR} -Des.default.path.conf=${CONF\_DIR} (code=exited, status=1/FAILURE)

I did not change the path or install anything special.
Thanks

You've upgraded from 1.7.3 to 2.0 or 2.1 or...? The stacktrace indicates that the error is related to plugins so I'd try removing any plugins (which probably need to upgraded). This looks like your syslog—have you looked in ES's own log for additional details?

The good thing with open-source are ... sources 😉
Check at
[https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/plugins/PluginsService.java#L95](https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/plugins/PluginsService.java#L95)
From the right branch according your ES version, you should find whats going bad.

Thank you all,
I removed the HQ plugin then the upgrade progress worked. !
