HI @Bala Vignesh N V Thanks a lot for your answer.
When I execute your query, I get almost only NULL values within my table (other are kind of binaries data).
I also tried with : "orc.compress"="ZLIB" and "orc.compress.size"=65536
But nothing changed. Any ideas ?

Hi, I'm new on hadoop and today I try to create a csv file from an orc file. I can display orc contents with : hive --orcfiledump file:///root/myORCfile and I got another text file with the original table structure (col names, types etc..) created from a "describe table" sql command. I also know how to export a table from hive to a local csv. However, I'm wondering if it exists any solution to convert my orc file into a simple hive table.
I also try to know if it is possible to directly convert orc to csv.
