Gentoo linux with Hortonworks Hadoop hadoop-1.1.2.23.tar.gz and Apache Hive 0.11d
Description
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:
