      Description

      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.
