Has anyone observed a problem when upgrading from ElasticSearch 1.0.3 to
1.1.2 regarding the cat shards (or cat indices)? We recently rolled this
out in one of our environments and experienced a NullPointerException (NPE)
for some of the cat API calls (for instance: cat/shards or cat/indices).
The good news is that this went away once all nodes were on the same
version.
My question: is it correct to assume that this is expected behavior? Also,
is there anything that I could do to mitigate this (upgrade faster ;)?
Problems experienced were with:
cat/shards
cat/indices
cat/nodes
Oddly, cat/indices/my-index?H did return the expected values (or at least
when I tested it did).
