Hi
I encountered the following problem:
Caused by: java.lang.IndexOutOfBoundsException: index (-2) must not be
negative

My environment is:
- Elasticserach 0.90.7
- 3 nodes in a cluster
- Send GET request with preference=_local
Looking into IndexShardRoutingTable class, it seems that "loc" is
an unexpected negative value at the following code. pickIndex method
returns a value of "counter"(incremental value). If "counter" achieves
Integer.MAX_VALUE, I think that "loc" is negative and then
activeShards.get(loc) throws the exception.
int index = pickIndex();
for (int i = 0; i < activeShards.size(); i++) {
int loc = (index + i) % activeShards.size();
If it's a bug, I'll file an issue.
Best regards,
shinsuke
