Subject [jira] [Commented] (SOLR-8129) HdfsChaosMonkeyNothingIsSafeTest failures
Date Fri, 22 Jan 2016 17:51:39 GMT


Yonik Seeley commented on SOLR-8129:

Opened SOLR-8586 for hashing all versions.

bq. These kind of reorders don't seem that common?

Seems way too common on HDFS (on my linux box at least).  

Even with SOLR-8586, big enough reorders can still cause other issues, such as going beyond
our delete window.  That would cause shards to get out-of-sync even when all the shards are
up and live (and hence we wouldn't catch it until the next time we did a version-hash for
some reason).
