Hi list,
after changing DIH to multi-theaded (4 threads) I get sometimes an exception.
This is not always the case and I never had any problems with single-threaded
at all.
I'm using Solr 3.5 but also tried branch_3x (3.6) and could see this with both
versions.
Don't know why this comes up after changing to multi-threaded.
No other errors at all.
This is when LogUpdateProcessor finishes and is going create the log message.
Whats wrong with this code?
public String getName(int idx) {
return (String)nvPairs.get(idx << 1);
}
Any idea how to trace this down?
