[jira] [Updated] (PHOENIX-2613) if any column of multi-part primary key is null, the Skip Scan may cause RegionServer scan indefinite loop

     [ https://issues.apache.org/jira/browse/PHOENIX-2613?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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:

@Test
public void testNullInfiniteLoop() throws Exception
{
	this.jdbcTemplate.update("drop table if exists NULL_TEST ");  \r\n
		
	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'");
		
}
