I am trying to create Hive table over Hbase table. Details shown below: HBase table has data like: Connected to: Phoenix (version 4.7) Driver: PhoenixEmbeddedDriver (version 4.7) Autocommit status: true Transaction isolation: TRANSACTION_READ_COMMITTED Building list of tables and columns for tab-completion (set fastconnect to true to skip)... 1341/1341 (100%) Done Done sqlline version 1.1.8 0: jdbc:phoenix:maxiqtesting1.lti.com:2181:/h> select * from HBASE_TEST_6JULY_1792409; +---------+---------+---------+ | FIELD0 | FIELD1 | FIELD2 | +---------+---------+---------+ | 1 | qq | 23 | | 2 | ee | 12 | | 3 | dd | 123| +---------+---------+---------+ 3 rows selected (0.139 seconds) 0: jdbc:phoenix:maxiqtesting1.lti.com:2181:/h> create Hive Table command: CREATE EXTERNAL TABLE HBASE_TEST_6JULY(FIELD0 int,FIELD1 string, FIELD2 int) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,0:FIELD1,0:FIELD2","hbase.table.default.storage.type" = "binary", 'serialization.format'='1') TBLPROPERTIES("hbase.table.name" = "HBASE_TEST_6JULY_1792409"); SELECT command on Hive table gives result as: hive> select * from HBASE_TEST_6JULY; OK -2147483647 qq -2147483625 -2147483646 ee -2147483636 -2147483645 dd -2147483525 Time taken: 0.963 seconds, Fetched: 3 row(s) The integer columns values are not displayed correctly. If I give all columns as String in hive then I am getting null for corresponding integer columns in HBase. On the other hand when I appended records in same hive table (over Hbase) by following query Insert in to HBASE_TEST_6JULY Select * From abc query, I can see the new records correctly while the old records stored in Hbase through Phoneix API have same issue. Is this a version related issue? Hadoop Version: 2.7.3.2.5.3.0-37(HBase 1.1.2) Phoneix: 4.7(HBase 1.1.3) Can anyone please help me and provide solution to read numeric/non-string columns with correct value by exposing Hive tables on HBase ?
