Hi again.  
While indexing my documents the following problem occured:

[2011-07-06 05:34:33,187][DEBUG][action.bulk] [Astra]  
[201009][4]: Failed to execute bulk item (index) [index {[201009]

That happens for only one document. Any idea why I happened?

The doc seems to be visible using:  
curl -XGET 172.17.0.223:9200/201009/message/211d779c-4e6c-4f9b-  
b74e-5cc502854732?pretty=1  
{  
"\_index" : "201009",  
"\_type" : "message",  
"\_id" : "211d779c-4e6c-4f9b-b74e-5cc502854732"  
}

But it is not visible by \_search.

Anyway, is there any possibility to know about this exception on the  
client side?  
Invoking BulkResponse#hasFailures() will be enought in case on some  
problems on the server side?

Ok, it seems to be a bug in ES 0.16.2 (unfortulately)

Simple use case shows that it is true:

curl -XPUT localhost:9200/test/message/211d779c-4e6c-4f9b-  
b74e-5cc502854732 -d '  
{  
"test":"test"  
}'

{"error":"ArrayIndexOutOfBoundsException[-48]","status":500}

curl -XPUT localhost:9200/test/message1/211d779c-4e6c-4f9b-  
b74e-5cc502854732 -d '  
{  
"test":"test"  
}'

Changing index type name or key makes the index to be properly  
persist.

curl -XPUT localhost:9200/test/message1/211d779c-4e6c-4f9b-  
b74e-5cc502854732 -d '  
{  
"test":"test"  
}'  
{"ok":true,"\_index":"test","\_type":"message1","\_id":"211d779c-4e6c-4f9b-  
b74e-5cc502854732","\_version":2}

curl -XPUT localhost:9200/test/message/211d779c-4e6c-4f9b-  
b74e-5cc502854731 -d '  
{  
"test":"test"  
}'  
{"ok":true,"\_index":"test","\_type":"message","\_id":"211d779c-4e6c-4f9b-  
b74e-5cc502854731","\_version":2}

The problematic line is:  
return dirtyLocks[Math.abs(uid.hashCode()) % dirtyLocks.length];

So when uid.hashCode() returns Integer.MIN\_VALUE then this negative  
value is returned. Which means that modulo also returns negative value  
(wrong).
