Anand updated PHOENIX-6623:
---------------------------
Description:
We are using below versions of Phoenix, HBase and Spark.
Phoenix - 4.7
HBase - 2.6.5
Spark - 2.4
Created a phoenix table by mentioning one of the field datatype as DATE and
TIMESTAMP in Phoenix using Squirrel SQL. DDL is given below.
CREATE TABLE IF NOT EXISTS NS_TEST.CUSTOMER_TBL (
"CID" INTEGER,
*"CDATE" DATE,*
"CTIMESTAMP" TIMESTAMP,
CONSTRAINT CUSTOMER_TBL_PK PRIMARY KEY ("ID"));
Upserted records using upsert command and below is the data in table.
|CID|CDATE |CTIMESTAMP |
|1 |*2021-11-21*|2022-01-18 18:30:33.896|
|2 |*2021-11-18*|2022-01-18 18:45:59.336|
|3 |*2021-11-17*|2022-01-18 19:01:04.265|
Now, reading data from above created table in pyspark shell. We have set
*spark.sql.session.timeZone=UTC* to spark while launching pyspark shell. Also,
we have set *phoenix.query.dateFormatTimeZone=UTC* in *hbase-site.xml* file. **
Below code snippet read data from phoenix via JDBC and it r{*}ead DATE datatype
field as one day less{*}.
>>> *df = spark.read.format("jdbc") *
*.option("driver", "org.apache.phoenix.jdbc.PhoenixDriver") *
*.option("url", "jdbc:phoenix:localhost:2181:/hbase-secure") *
*.option("dbtable", "(SELECT CID, CDATE, CTIMESTAMP) q") *
*.load()*
>>>df.printSchema()
root
|-- CID: integer (nullable = true)
|-- *CDATE: date* (nullable = true)
|-- CTIMESTAMP: timestamp (nullable = true)
>>>{*}df.select('{*}').show(truncate=False)\{*}
|CID|CDATE |CTIMESTAMP |
|1 |*2021-11-20*|2022-01-18 18:30:33.896|
|2 |*2021-11-17*|2022-01-18 18:45:59.336|
|3 |*2021-11-16*|2022-01-18 19:01:04.265|
We have also tried using phoenix data source instead of JDBC and below is the
code snippet. It also read DATE datatype field as one day less.
>>>{*}df = spark.read.format("org.apache.phoenix.spark") {{*}}
*.option("table", "NS_TEST.CUSTOMER_TBL") *
*.option("zkUrl", "jdbc:phoenix:localhost:2181:/hbase-secure") *

|3 |*2021-11-16*|2022-01-18 19:01:04.265|
Please help us on this issue why Phoenix Spark reading DATE datatype field
value as {*}one day less{*}.
