Hi Karl,
Above changes provide great throughput for crawling of local system.
Now i tried running job for shared drive. I know things wont be as fast as
local drive. But i wanted to look how things change with shared drive.
When i ran job with shared drive it errored out with message "Error: IO
Error: \\devshare\devl\jneiper\Testcases for Galaxy.doc: The specified
network name is no longer available.".
This is not Solr error because i could find in Solr log.
I found error in MCF log. please find below stack trace:
ERROR 2014-08-01 14:41:17,531 (Worker thread '88') - Exception tossed: IO
