I have a nice setup with a Hive thrift server running in a docker
container on Mesos. It works pretty well, but something, I believe in
how HAProxy works with the connection, is causing the thrift server
connection to die after a time. Basically, I can run a few queries,
but after 2 or 3, or specifically after a longer query, I get the
error below indicating End of File on the connection. Then no more
connections work until I reestablish the connection to the thrift
server. I've tried looking in logs. the thrift server std err logs
show no issues. I am guess I need to dig into haproxy logs, but I am
not seeing any issues in syslog so far. I'd love any pointers on how
to trouble shoot this. By the way, I have MySQl, hive metastore, and
a minecraft server all running on Mesos/Docker with no issues, not
sure why the thrift server is so sensitive.
