--------------------------------------------
Summary: Modify TSaslTransport to ignore TCP health checks from
loadbalancers
Key: THRIFT-2268
URL: https://issues.apache.org/jira/browse/THRIFT-2268
Project: Thrift
Issue Type: Improvement
Components: Java - Compiler
Affects Versions: 0.9
Reporter: Thiruvel Thirumoolan
Priority: Minor
Fix For: 0.9.2, 1.0
Thrift Server with TSaslTransport throws TTransportExceptions when deployed
behind a hardware load balancer.
We have deployed thrift servers HiveServer2 and HCatalog (both Apache Hive
components) behind hardware load balancers. The load balancer does a TCP health
check on the port where the thrift server (HiveServer2/HCatalog) is running.
Some of the load balancers complete the TCP handshake and then close the
connection without any data and therefore thrift has to handle it this
connection. Because the TCP health check happens very frequently - about 10-20
times a minute, the logs are filled with TTransportExceptions. The current
logic assumes a valid header and if its not present (TCP health check), then it
keeps throwing exceptions.
This JIRA attempts to ignore these which does not have a valid header.
