Hi Team,
I need snappy compression to be used for the Hbase table but it is not
creating the table as SNAPPY compressed when I look through the DDL's in
the Hbase shell.
Also while loading the data the size of the data remains the same for
SNAPPY or NONE.
Please help if I am missing anything.
Details Below:-
CREATE TABLE IF NOT EXISTS adv_cat (
cat varchar ,
domain VARCHAR
CONSTRAINT PK PRIMARY KEY (cat,domain)
);
DDL:- describe 'ADV_CAT_GZ'
