> We are using below versions of Phoenix, HBase and Spark.

> 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 ("CID"));
> Upserted records using upsert command and below is the data in table.

> |CID|CDATE |CTIMESTAMP |

> Now, reading data from above created table in pyspark shell. We have set
