Description

Scenario:

• New 4.15 client
  • create table ns1.test (pk1 integer not null, pk2 integer not null, pk3 integer not null, v1 float, v2 float, v3 integer CONSTRAINT pk PRIMARY KEY (pk1, pk2, pk3));
  • create local index l1 on ns1.test(v1);
• Old 4.14.x client
  • explain select count(*) from test t1 where t1.v1 < 0.000001;

Result:

0: jdbc:phoenix:localhost> explain select count(*) from ns1.test t1 where t1.v1 < 0.000001;
Error: ERROR 201 (22000): Illegal data. Expected length of at least 8 bytes, but had 2 (state=22000,code=201)
java.sql.SQLException: ERROR 201 (22000): Illegal data. Expected length of at least 8 bytes, but had 2
