Subject More problems (now jetty errorrs) with SolrCloud
Date Fri, 22 Jan 2016 15:23:32 GMT
Hi,

This morning one of the 2 nodes of our SolrCloud went down. I've tried
many ways to recover it but to no avail. I've tried to unload all cores
on the failed node and reload it after emptying the data directory,
hoping it would sync from scratch. The core is still marked as down and
no data is downloaded.

I get a lot of messages like to following ones in the log:

WARN  - 2016-01-22 14:14:28.535; [   ]
org.eclipse.jetty.http.HttpParser; badMessage: 400 Unknown Version for

org.apache.solr.common.SolrException;
null:org.apache.solr.common.SolrException: Unexpected method type: [...
truncated json data, presumably from a document being updated ...]POST
etc.

I've restarted all nodes in zk and SolrCloud, and reloaded all cores on
the main node (that is, the one that seems to work).


After some research, I saw that the zk timeout is set to 60 sec. in the
solr config, but at least one entry in the gc logs mentions 134 sec.
However, I noticed that the zk logs states a negociated timeout of 30 sec...

Here are my questions:
- Are the log entries shown above related to the zk session timeout, or
should I look elsewhere?
- How to make sure the timeout negociated with zk matches the value from
the solr config?
- What parameter(s) would allow to reduce the gc execution time,
presumably at the expense of a more frequent gc?

Thanks!
