4 core cpu, 15gb memory. 2 thrift server behind load balancer
Description
Hi All,
Please review the following problem, I also posted same in the hive-user group, but didnt got any response yet.
This is happening quite frequently in our environment.
So, it would be great if somebody can see and advise.
I'm using Hive Thrift Server in Production which at peak handles around 500 req/min.
After certain point the Hive Thrift Server is going into the no response mode and throws
Following exception
"org.apache.hadoop.hive.ql.metadata.HiveException: org.apache.thrift.transport.TTransportException: java.net.SocketTimeoutException: Read timed out"
As the metastore we are using MySQL, that is being used by Thrift server.
The design / architecture is like this:
Oozie – > Hive Action --> ELB (AWS) --> Hive Thrift ( 2 servers) --> MySQL (Master) – > MySQL (Slave).
Software versions:
Hive version : 0.10.0
Hadoop: 1.2.1
Looks like when the load is beyond some threshold for certain operations it is having problem in responding.
As the hive jobs sometimes fails because of this issue, we also have a auto-restart check to see if the Thrift server is not responding, it stops / kills and restart the service.
Other tuning done:
Thrift Server:
Given 11gb heap, and configured CMS GC algo.
MySQL:
Tuned innodb_buffer, tmp_table and max_heap parameters.
So, can somebody please help to understand, what could be the root cause for this or somebody faced the similar issue.
I found one related JIRA :https://issues.apache.org/jira/browse/HCATALOG-541
But this JIRA shows that Hive Thrift Server shows OOM error, but in my case I didnt see any OOM error in my case.
Regards,
Manish
