-----------------------------------
Summary: Infinite loop with ORC file and Hive 0.1
Key: HIVE-5235
URL: https://issues.apache.org/jira/browse/HIVE-5235
Project: Hive
Issue Type: Bug
Affects Versions: 0.11.0
Environment: Gentoo linux with Hortonworks Hadoop
hadoop-1.1.2.23.tar.gz and Apache Hive 0.11d
Reporter: Iván de Prado
Priority: Blocker
We are using Hive 0.11 with ORC file format and we get some tasks blocked in
some kind of infinite loop. They keep working indefinitely when we set a huge
task expiry timeout. If we the expiry time to 600 second, the taks fail because
of not reporting progress, and finally, the Job fails.
That is not consistent, and some times between jobs executions the behavior
changes. It happen for different queries.
We are using Hive 0.11 with Hadoop hadoop-1.1.2.23 from Hortonworks. The taks
that is blocked keeps consuming 100% of CPU usage, and the stack trace is
always the same consistently. Everything points to some kind of infinite loop.
My guessing is that it has some relation to the ORC file. Maybe some pointer is
not right when writing generating some kind of infinite loop when reading. Or
maybe there is a bug in the reading stage.
More information below. The stack trace:

We have seen the same stack trace repeatedly for several executions of jstack.
