---------------------------------------------------------------
I went through logs at
https://jenkins.thetaphi.de/job/Lucene-Solr-6.x-MacOSX/429/consoleFull
If PeerSync was unsuccessful I would expect to see a line like
{{o.a.s.u.PeerSync Fingerprint comparison: -1}}
However, I don't see such line. I could think of two scenarios that could break
the test
* data directory could get deleted while a node is brought down, since data
directory is created in {{temp}}. Upon restart replica would have no frame of
reference and will have to fall back on replication.
* we need a better check than relying number of requests made to
{{ReplicationHandler}}
was (Author: praste):
I went through logs in the failed test email notification but those are
truncated. Where can I look at the entire build.log for the test.
Only thing I could think of at this point is data directory could get deleted
while a node is brought down, since data directory is created in {{temp}}. Upon
restart replica would have no frame of reference and will have to fall back on
replication.

> I found that Peer Sync fails if a node restarts and documents were indexed
> while node was down. IndexFingerPrint check fails after recovering node
> applies updates.
> This happens only when node restarts and not if node just misses updates due
> reason other than it being down.
> Please check attached patch for the test.
