Gotcha.
Columns are quite dynamic in my case, but since I need to fetch rows first
anyways; a KeyOnlyFilter to first find them and then overwrite values will
do just fine.

I didn't mean to set the version to null, I meant to include a revision of
the column whose contents are empty. This empty revision will Still be

I tried the null-version trick but must be doing something wrong. How do I
set version to null on a column? Isnt version equal to the timestamp
(primitive long)?
Setting timestamp to 0 and
That's right.
In HBase 0.94 and trunk, check out the following API in HRegion:
public void mutateRowsWithLocks(Collection mutations,
Collection rowsToLock) throws IOException {
It allows you to combine Put's and Delete's for a single region, atomically.

Hi
I'm trying to use Put operations to replace ("set") already existing rows
by nullify certain columns and qualifiers as part of an Put operation.
The reason I want to do this is 1) keep the operation atomic/consistent 2)
avoid latency from first doing Delete then Put.
Is there some way to do t
