Lars Hofhansl commented on HBASE-14098:
---------------------------------------
Awesome!
Cache flush stalls can also be avoided by configuring the Linux disk cache.
Could you do a {{sysctl -a | grep dirty}} on one of the boxes and paste
vm.dirty_background_ratio, vm.dirty_background_bytes, and vm.dirty_ratio here?
Just curious :) Your previous comment made sense anyway. Caching anything that
is usually read sequentially and larger than the available RAM never makes
sense.
