We are upgrading our ES server from 0.2.0 to 1.2.1 using the cluster
restart upgrade steps here
<http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup-upgrade.html#restart-upgrade>.
We have 2 nodes as part of our cluster. We disabled allocation on both
nodes before the upgrade and then upgraded the servers.
However after starting both nodes, when we attempt to re-enable allocation
it seem like Node2 just doesn't work with shard reallocation and throws the
following error. The errors just keep happening so we eventually had to
turn off replication again and now we are getting by with a single node in
the cluster with no replication.
Below is the stacktrace of the NullPointerException when trying to enable
allocation. Any pointers to help with solving this would be greatly
appreciated. I can provide more details if needed.
