Is there any guidance on finding a needle-in-a-haystack input error in a ton of data? For example, I've got one row in a csv file amongst thousands containing tens of millions of rows that has as its first column a string instead of a number like it should be. Is there some way to get Drill to tell me which file that row is in? Something like the dirX columns would work, since I can select for the row.
Note, these are CSV files hosted in S3. Thanks, Wes
