Hive interaction with speculative execution is broken
-----------------------------------------------------
Key: HADOOP-4097
URL: https://issues.apache.org/jira/browse/HADOOP-4097
Project: Hadoop Core
Issue Type: Bug
Components: contrib/hive
Reporter: Joydeep Sen Sarma
Assignee: Joydeep Sen Sarma
Priority: Critical
Hive does not cleanup output files when tasks are killed. With speculative
execution, partial result files may get left behind. The commit step of the
results should detect and remove any partial output files.
