my target hive table using informatica etl tool.

updates not supported in hive earlier versions. how should updates records in scenario. ok go hive update feature using hive acid , transaction feature.

informatica supports updates hive tables informatica 9.6 hf3 version provided tables support acid, more information can refer link (https://cwiki.apache.org/confluence/display/hive/hive+transactions), instead of doing this, rather in 2 step process,

1) identify records exist in target , records exist in stage data 2) merge these 2 , load them temporary table. 3) re-name temporary table actual target table name

the above work scd type 1 implementations
