Pyspark: pushing filter by date against apache phoenix

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)

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

Typically questions are asked on Apache dev lists and issues are reported in JIRA. Your JIRA was kindly responded to (within 4 hours) here: https://issues.apache.org/jira/browse/PHOENIX-3664?focusedCommentId=15863720&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15863720

Not a big fan of the shotgun approach of tweeting + stack overflow + dev list + JIRA. Please keep in mind that the folks that respond all have day jobs.
