chenglei updated PHOENIX-2613:
------------------------------
Description:
In pheonix 4.6,any column of multi-part primary key can be null.If a table has
one row which has a column of multi-part primary key is null, when I do a
query,the Skip Scan may cause RegionServer scan indefinite loop,just like the
following unit test:
{quote}
public void testNullInfiniteLoop() throws Exception
{
this.jdbcTemplate.update("drop table if exists NULL_TEST ");
\\
this.jdbcTemplate.update(
"create table NULL_TEST"+
"("+
"CREATETIME VARCHAR,"+
"ACCOUNTID VARCHAR,"+
"SERVICENAME VARCHAR,"+
"SPAN.APPID VARCHAR,"+
"CONSTRAINT pk PRIMARY
KEY(CREATETIME,ACCOUNTID,SERVICENAME)"+
")");
this.jdbcTemplate.update("upsert into
NULL_TEST(CREATETIME,SERVICENAME,SPAN.APPID)
values('20160116141006','servlet','android')");
this.jdbcTemplate.update("upsert into
NULL_TEST(CREATETIME,ACCOUNTID,SERVICENAME,SPAN.APPID)
values('20160116151006','2404787','jdbc','ios')");
this.jdbcTemplate.queryForList("select * from NULL_TEST where
CREATETIME>='20160116121006' and CREATETIME<='20160116181006' and
ACCOUNTID='2404787'");
}
