Hive table outdated after Sqoop incremental import












1















I'm trying to do a Sqoop incremental import to a Hive table using "--incremental append".



I did an initial sqoop import and then create a job for the incremental imports.
Both are executed successfully and new files have been added to the same original Hive table directory in HDFS, but when I check my Hive table, the imported observations are not there. The Hive table is equal before the sqoop incremental import.



How can I solve that?
I have about 45 Hive tables and would like to update them daily automatically after the Sqoop incremental import.



First Sqoop Import:



sqoop import 

--connect jdbc:db2://... 

--username root 

-password 9999999 

--class-name db2fcs_cust_atu 

--query "SELECT * FROM db2fcs.cust_atu WHERE $CONDITIONS" 

--split-by PTC_NR  

--fetch-size 10000 

--delete-target-dir 

--target-dir /apps/hive/warehouse/fcs.db/db2fcs_cust_atu 

--hive-import 

--hive-table fcs.cust_atu 

-m 64;


Then I run Sqoop incremental import:



sqoop job 

-create cli_atu 

--import 

--connect jdbc:db2://... 

--username root 

--password 9999999 

--table db2fcs.cust_atu 

--target-dir /apps/hive/warehouse/fcs.db/db2fcs_cust_atu 

--hive-table fcs.cust_atu 

--split-by PTC_NR 

--incremental append 

--check-column TS_CUST 

--last-value '2018-09-09'
