hello, I have a table created and loaded under carbon1.3.0 and i'm upgrading to carbon1.3.1 using refresh table. following is my step: 1. copy old table's hdfs location to a new direcotry. /user/xx/prod_inst_cab-->/user/xx/prod_inst_cab_backup 2. hive -e "drop table xx.prod_inst_cab" 3. cc.sql("drop table xx.prod_inst_cab") (ps: initial carbonsession using '/user/xx' location; like val cc = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("hdfs://ns1/user/xx") ) 4. hdfs dfs -rmr -skipTrash /user/xx/prod_inst_cab and copy /user/xx/prod_inst_cab_backup --> /user/xx/prod_inst_cab 5.cc.sql("refresh table xx.prod_inst_cab").show as well as cc.sql("refresh table xx.prod_inst_cab_backup").show
when perform 1.cc.sql("select count(1) from xx.prod_inst_cab").show result is 0 2.cc.sql("select count(1) from xx.prod_inst_cab_backup").show result is right,but all columns of all records is "null" Am i missing some details? sunerhan1...@sina.com
