Tassilo Klein created SPARK-5363:
------------------------------------
Summary: Spark 1.2 freeze without error notification
Key: SPARK-5363
URL: https://issues.apache.org/jira/browse/SPARK-5363
Project: Spark
Issue Type: Bug
Affects Versions: 1.2.0
Reporter: Tassilo Klein
Priority: Critical
Fix For: 1.2.1, 1.2.2
After a number of calls to a map().collect() statement Spark freezes without
reporting any error. Within the map a large broadcast variable is used.
The freezing can be avoided by setting 'spark.python.worker.reuse = false'
(Spark 1.2) or using an earlier version, however, at the prize of low speed.
