Hello @Madhureddy    Thanks for using Cloudera Community. Based on the post, Table "Meterevents" was loaded with 3K records & an Insert Select Operation was performed against "events_Hbase" from "Meterevents" table. The "events_Hbase" table is showing 1200 records.    We wish to check upon the following details: 1. Connect to HBase Shell & confirm the count of "HbaseEvents" table, 2. If the count of "HbaseEvents" table is 1200, Check for the Uniqueness of the 1st Column being used as ":key" while loading the Table. It's likely the RowKey is being repeated, causing an updated Version being utilised, thereby reducing the row-count.  3. Your team can check upon the above by creating 2 Tables & insert 10 unique rows (By RowKey Column) into 1 Table with 10 rows (Having, 5 Unique RowKey Values) into the 2nd Table. Next, Create 2 Hive Table using HBaseStorageHandler & perform the Insert Select SQL. Then, Check the Row Count.    - Smarak ... View more
