Hi,

We could not overwrite a file inside hive table folder. What is the command to over write it.

What do you mean by "a file"? If your HDFS dir contains several file
and you want to overwrite one, then no way you can do it with HiveQL.
You can check out this link and see if it suits you.

My way of exporting hiveql result as a single is this:
echo "some,column,name">some.file
hive -S -e "select some, column, name from some_table"|sed -e
"s/\t/,/" >> some.file

Hi,

I think you could try to drop partition and create a new partition if
you table is partitioned
