------------------------------
Summary: High spark.executor.memory causes wrong result
Key: SPARK-11556
URL: https://issues.apache.org/jira/browse/SPARK-11556
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.1
Reporter: Younes
When setting spark.executor.memory too high, queries starts to return wrong
result silently.
My setting: 48GB ram servers
When setting spark.executor.memory to 32G, any select on text column on parquet
files, truncates the 1st 8 chars.
When setting it to 30G, the problem goes away.
