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).
