I'm trying to migrate a server with Solr 4.7.2 on it. I have a Solr 4.10.2 with 4 cores running which is the new machine. I have an importer running on the old machine that poses no problem. However, when trying to run the importer on the new machine, I get a
java.io.EOFException : Can not read response from server.Expected to read 848 bytes, read 576 bytes before connection was unexpectedly lost.
I've thrown some extra parameters into the data-config.xml in the hopes it would fix the problem, but to no avail :
defaultFetchSize="30" useCursorFetch="true" autoReconnect="true" tcpKeepAlive="true" connectionTimeout="120000" stream="true"
The file syntax of the data import must be correct, since the import runs fine on exactly the same MySQL table with less records in it on the same machine.
I've been trying to debug this for hours and hours now, and can't find the solution. Can anyone help me with any pointers on how to properly find the cause for this?
