> create table AN_BASEINFO
> using org.apache.phoenix.spark
> OPTIONS(table "AN_BASEINFO ", zkUrl "172.16.12.82:2181")
> and
> create table AN_SUP_BASEINFO
> using org.apache.phoenix.spark
> OPTIONS(table "AN_SUP_BASEINFO ", zkUrl "172.16.12.82:2181")
> IN SparkSQL I execute a sql use lef outer join,the sql is :
> {color:red}{color:#f79232}_
> *select
> a.anchedate,b.womempnumdis,b.holdingsmsgdis
> from
> AN_BASEINFO a
> left outer join AN_SUP_BASEINFO b
