wangzhenhua a29ee55aaa [SPARK-18815][SQL] Fix NPE when collecting column stats for string/binary column having only null values ... ## What changes were proposed in this pull request? During column stats collection, average and max length will be null if a column of string/binary type has only null values. To fix this, I use default size when avg/max length is null. ## How was this patch tested?
