Subject Gora CassandraStore is not thread safe?
Date Wed, 10 Aug 2011 19:43:46 GMT
Has anyone tested the CassandraStore in gora 0.2 using multiple threads?  The nutch 2 fetcher
architecture has many threads writing to one GoraRecordWriter and I am getting concurrent
modification errors like below.

Caused by: java.util.ConcurrentModificationException
