-------------------------------------
Summary: ClassCastException from Pig loader
Key: PHOENIX-3240
URL: https://issues.apache.org/jira/browse/PHOENIX-3240
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.8.0
Reporter: YoungWoo Kim
I'm loading data from Hive table to Phoenix table in using Phoenix-Pig
integration. my pig script looks like following:
{code}
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');
{code}
If the source table has timestamp, MapReduce job for Pig script does not work:
{noformat}
