Hey all, I have some Parquet files that I believe were made in a Map Reduce
job and work well in Impala, however, when I read them in Drill, the fields
that are strings come through as [B@25ddbb etc. The exact string
represented as regex would be /\[B@[a-f0-9]{8}/ (Pointers maybe?)
Well, I found I can cast those fields as Varchar... and get the right
data... is this the right approach? Why is this happening? Performance
wise am I hurting something by doing the cast to Varchar?
Any thoughts would be helpful...
John
