Updated to 1.6.1 and seeing an issue. Time to jump to 1.7?

Elastic Stack Logstash
1

I have four ES nodes, one of which is a client, and is streaming archived log data into the cluster.

After upgrading all nodes to 1.6.1. [1] I restarted my intake script. While it appears to be adding data, it's also feeding this back to stdin. Is this a problem?

Should I make the lightspeed jump to 1.7? Move everyone back to 1.6 ?

[1] I added a third data node, which yum helpfully installed at 1.6.1 which caused issues with shards. The previous three nodes installed, weeks before, with 1.6.0.

That's a Logstash problem not an ES one.

What version of LS are you on?

3 
# /opt/logstash/bin/logstash --version
logstash 1.5.0
4

Upgrade LS to >1.5.2, there are some fixes there that will help.

Yum offered to update me to 1.5.3. After I did so this was thrown into /var/log/logstash. It seems to be feeding the bits into elasticsearch okay ..

 cat logstash.err
'[DEPRECATED] use `require 'concurrent'` instead of `require 'concurrent_ruby'`
