https://issues.apache.org/jira/browse/SPARK-3106
I'm having the saming errors described in SPARK-3106 (no other types of errors confirmed), running a bunch sql queries on spark 1.2.0 built from latest master HEAD. Any updates to this issue? My main task is to join a huge fact table with a dozen dim tables (using HiveContext) and then map it to my class object. It failed a couple of times and now I cached the intermediate table and currently it seems working fine... no idea why until I found SPARK-3106 Cheers, -- Jianshi Huang LinkedIn: jianshi Twitter: @jshuang Github & Blog: http://huangjs.github.com/
