FAQ
I have this situation where a few (like, 3-4 out of 84) nodes misbehave.
Very long GC pauses, dropping out of cluster etc.

This happens while loading data (via CQL), and analyzing metrics it
looks like on these few nodes, a lot of hints are being generated close
to the time when they start to misbehave.

Since this is Cassandra 2.0.13 which have a less than optimal hints
implementation, largs numbers of hints is a GC troublemaker.

Again looking at metrics, it looks like hints are being generated for a
large number of nodes, so it doesn't look like the destination nodes are
at fault. So, I'm confused.

Any Hints (pun intended) on what could cause a few nodes to generate
more hints than the rest of the cluster?

Regards,
\EF
