             Summary: Pyspark: pushing filter by date against apache phoenix
                 Key: PHOENIX-3664
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3664
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.7.0
         Environment: Azure HDIndight - pyspark using phoenix client.
            Reporter: Pablo Castilla


I am trying to filter by date in apache phoenix from pyspark. The column in phoenix is created
as Date and the filter is a datetime. When I use explain I see spark doesn't push the filter
to phoenix. I have tried a lot of combinations without luck.

Any way to do it?

df = sqlContext.read \
   .format("org.apache.phoenix.spark") \
  .option("table", "TABLENAME") \
  .option("zkUrl",zookepperServer +":2181:/hbase-unsecure" ) \
  .load()
print(df.printSchema())

startValidation = datetime.datetime.now()

print(df.filter(df['FH'] >startValidation).explain(True))

Results:
root
 |-- METER_ID: string (nullable = true)
 |-- FH: date (nullable = true)

None

if I set the FH column as timestamp it pushes the filter but throws an exception:
