Hi, I had a table with over 100 million records and delimited by | and also separated by quotes, so i used csvserde to ignore quotes to write into hive table. After succesfully done, count(*) and inserting into an orc table is taking forveer and stuck at 0%
I though serde is creating performance issues and deleted quotes fromt he text file and loaded into a regular hive text table. I can do a count(*) on it but writing into an ORC table is stuck at 0% ... i am not sure why. Please help
data size is 30GB and 100million rows.
Thanks so much.
