Read query slows down when a node goes down

[Parag Patel]

Hi,

We have a six node cluster running DataStax Community Edition 1.2.9.  From our 
app, we use the Netflix Astyanax library to read and write records into our 
cluster.  We read and write with QUARUM.  We're experiencing an issue where 
when a node goes down, we see our read queries slowing down in our app whenever 
a node goes offline.  This is a problem that is very reproducible.  Has anybody 
experienced this before or do people have suggestions on what I could try?

Thanks,
Parag
