Hi,
I wrote a java tool to convert part of our data from a mysql-database
into riak. As this tool is running while our system is still up, it
needs to replay all modifications done in the mysql database, during
these modifications I sometimes get this exception from the riak client:
com.basho.riak.client.convert.ConversionException: java.io.EOFException:
No content to map to Object due to end of input
com.basho.riak.client.convert.ConversionException: java.io.EOFException:

... 7 more
it only happens once every few thousand updates and if I check the
object from the cmdline I only get a 404.
Any ideas what might cause this and how to fix/workaround it?
