> I ran the following queries in drill:
> explain plan for select cast(row_key as integer) voter_id,
> convert_from(onecf['name'], 'UTF8') name, cast(twocf['age'] as integer) age,
> cast(twocf['registration'] as varchar(20)) registration,
> cast(threecf['contributions'] as decimal(6,2)) contributions,
> cast(threecf['voterzone'] as integer) voterzone,cast(fourcf['create_date'] as
> timestamp) create_date from voter where onecf['name'] not similar to
> '%(young|u|a)%';
> explain plan for select cast(student.onecf['name'] as varchar(35)) name,
> cast(student.twocf['age'] as integer) age, cast(student.threecf['gpa'] as
> decimal(4,2)) gpa, cast(voter.twocf['registration'] as varchar(20))
> registration from student join voter on (student.onecf['name'] =
> voter.onecf['name']) where cast(student.twocf['age'] as integer) = 70;
> explain plan for select cast(student.onecf['name'] as varchar(35)) name,
> cast(student.twocf['age'] as integer) age, cast(student.threecf['gpa'] as
> decimal(4,2)) gpa, cast(voter.twocf['registration'] as varchar(20))
> registration from student join voter on (student.onecf['name'] =
> voter.onecf['name']) where cast(student.twocf['age'] as integer) > 70;
> The explain plans for each of the query shows the following:
> "graph" : [ {
> "pop" : "hbase-scan",
> "@id" : 5,
> "hbaseScanSpec" : {
> "tableName" : "voter",
> "startRow" : null,
> "stopRow" : null,
> "serializedFilter" : null
> },
> Looks like the serializedFilter should not be null.
