Description

I'm loading data from Hive table to Phoenix table in using Phoenix-Pig integration. my pig script looks like following:

T = LOAD 'mydb.$TBL' USING org.apache.hive.hcatalog.pig.HCatLoader();

STORE T into 'hbase://MYSCHEMA.$TBL' using
    org.apache.phoenix.pig.PhoenixHBaseStorage('i004,i005,i006','-batchSize 1000');

If the source table has timestamp, MapReduce job for Pig script does not work:

ERROR 0: java.lang.ClassCastException: org.joda.time.DateTime cannot be cast to org.apache.phoenix.shaded.org.joda.time.DateTime
