Subject Re: Hive Metastore Server 0.9 Connection Reset and Connection Timeout errors
Date Mon, 29 Jul 2013 18:29:45 GMT
Thanks Nitin!

We have simiar setup (identical hcatalog and hive server versions) on a
another production environment and dont see any errors (its been running ok
for a few months)

Unfortunately we wont be able to move to hcat 0.5 and hive 0.11 or hive
0.10 soon.

I did see that the last time we ran into this problem doing a netstat-ntp |
grep ":10000" see that server was holding on to one socket connection in
CLOSE_WAIT state for a long time
 (hive metastore server is running on port 10000). Dont know if thats
relevant here or not

Can you suggest any hive configuration settings we can tweak or networking
tools/tips, we can use to narrow this down ?

Thanks
Agateaaa
