Apache Phoenix Upsert not working while trying to update null/empty columns

Step1: Update a column with null/'' value . Upsert into abc.tablename (Rowkeycombo1, Rowkeycombo2, columnname) values (123,to_date('1988-08-06'),null);

This works fine and the column then appears to have no data while doing a select.

Step2:Update the same column with a valid value. Upsert into abc.tablename (Rowkeycombo1, Rowkeycombo2, columnname) values (123,to_date('1988-08-06'),'TRYVAL'); Shows 1 row affected but the column still appears null/empty.

However there is no issue while updating a column which has a valid value to any other value.

I'm very new to Phoenix and hbase so I'm at a loss here.

Hbase does not store NULL. Actually it stores nothing when you give null. So output you are getting is expected.

Hello, I know this is aged topic... but I have the same issue.

I've not understood the answer from @schhabra1 : ok, hbase does not store NULL, but with "step2" @ananya_antony is trying to upsert the previous value...

is there any setting to configure in order to update previously "not stored column" with a new "not null" value?

 

can anybody give me some clues please? thanks

Hi,

This a BUG from Phoenix 

if I use upsert with null value, it "insert" the field with 0x00 0x00 bytes values and we cannot change
