zzcclp opened a new pull request #3399: [CARBONDATA-3527] Fix 'String length cannot exceed 32000 characters' issue when load data with 'GLOBAL_SORT' from csv files which include big complex type data
URL:
https://github.com/apache/carbondata/pull/3399
**Problem:**
When complex type data is used more than 32000 characters to indicate in csv file, and load data with 'GLOBAL_SORT' from these csv files, it will throw 'String length cannot exceed 32000 characters' exception.
**Cause:**
Use 'GLOBAL_SORT' to load data from csv files, it reads files and firstly store data in StringArrayRow, the type of all data are string, when call 'CarbonScalaUtil.getString' in 'NewRddIterator.next', it will check the length of all data and throw 'String length cannot exceed 32000 characters' exception even if it's complex type data which store as more than 32000 characters in csv files.
**Solution:**
In 'FieldConverter.objectToString' (called in 'CarbonScalaUtil.getString'), if the data type of field is complex type, don't check the length.
