Type conversion pig hcatalog
apache-pig, hcatalog, hive
Solution
The problem is that hcatalog doesn’t support timestamp type. It will be supported under hive 0.13, they have an issue about this problem that was already solved, you can see the issue in https://issues.apache.org/jira/browse/HIVE-5814
Problem
I use HCatalog version 0.4. I have a table in hive 'abc' which has a column with datatype 'timestamp'. When i try to run a pig script like this "raw_data = load 'abc' using org.apache.hcatalog.pig.HCatLoader();" i get an error saying "java.lang.TypeNotPresentException: Type timestamp not present".
