Lots of DNS queries from client
-------------------------------
Key: HBASE-4220
URL: https://issues.apache.org/jira/browse/HBASE-4220
Project: HBase
Issue Type: Bug
Components: client
Affects Versions: 0.92.0
Reporter: Todd Lipcon
Priority: Critical
Fix For: 0.92.0
In running a YCSB workload, I managed to DDOS a DNS server since it seems to be
flooding lots of DNS requests. Installing nscd on the client machines improved
throughput by a factor of 6 and stopped killing the server. These are
long-running clients, so it's not clear why we do so many lookups.
