On Oracle Big Data Appliance BDR Replication Corrupts Target Hive Table
(Doc ID 2000461.1)
Last updated on NOVEMBER 28, 2019
Applies to:Big Data Appliance Integrated Software - Version 4.1.0 and later
BDR hive replication setup from CDH5.3.0 to CDH5.3.0 works first time. Once data is added to source table then replication job corrupts target table.
- Source table is created as CTAS from partitioned table.
Test case is:
- Populate source table with data
- Run replication ( works ok, SELECT on target is ok )
- Add more data to source ( INSERT from partitioned source table )
- Run replication
FAILED: NullPointerException null
Also error occurs depending on how data is loaded into source table. If data is loaded via Hive LOAD statement issue doesn't occur. If via INSERT statement then select fails on target table.
