I am trying to understand if I should be concerned about this warning: "WARN Utils:66 - Truncated the string representation of a plan since it was too large. This behavior can be adjusted by setting 'spark.debug.maxToStringFields' in SparkEnv.conf"
It occurs while writing a data frame to parquet. Has any one on this list looked into this warning before and could help explain what it means? Thank you for your help, Henry
