Missing Indexes After upgrade

Elastic Stack Elasticsearch
1

We upgraded our ES version to RC1.0 from 0.90.3. After restarting ES only
half of our indexes were showing up. The indexes were still on the
filesystem but were not being recognized by ES. Any ideas to what went
wrong?

There was one reoccurring error in the log:
Message not fully read (request) for [] and action [], resetting.

But it doesn't seem like this has anything to do with our data not being
available. All nodes report a version of 1.0.0.RC1, and there are no other
clusters or ES nodes on the network.

Ryan,

Please check and and verify that every single node in your cluster has:

  1. Same ES version

  2. Same exact Java version (i.e. whatever is displayed when running java
    -version)

These have both been confirmed. We are running Java 1.7.0_15.

Hey,

can you start with more logging and check the elasticsearch logfile, if any
more suspicious messages occur (maybe including a stacktrace), which might
help here?
Also, just to verify, eveything runs with correct version, please paste:

curl 'localhost:9200/_nodes/jvm?pretty' | grep version
