We have a kudu table with size about 120GB, when we try to backup the kudu to impala and stored as parquet on hdfs
create table parquet_backup stored as parquet as select * from kudu_table but the two numbers we get by running select count(1) from kudu_table select count(1) from parquet_backup is Not equal. So my question is whether the result of count(1) is an estimated number or something is wrong when we try to backup the kudu table?
