https://github.com/apache/carbondata/pull/2873 [WIP] Fix partition load issue when custom location is added.
Problem:
Load files from carbonfile format when custom partition location is added
Reason:
Carbon has its own filename for each carbondata file, it does not use the filename proposed by spark. And also it has extra index file need to be created. In case of custom partition location sparks keep track the files of name which creates and move them. But carbon has different files created and maintained, that creates the filenot found exception.
Solution:
Use custom protocol to manage commit and folder location for custom partition location.
