Subject [jira] [Created] (PHOENIX-5107) Querying dynamic columns for an immutable table with SINGLE_CELL_ARRAY_WITH_OFFSETS storage scheme throws an exception
Date Mon, 21 Jan 2019 19:20:00 GMT
Chinmay Kulkarni created PHOENIX-5107:
-----------------------------------------

             Summary: Querying dynamic columns for an immutable table with SINGLE_CELL_ARRAY_WITH_OFFSETS
storage scheme throws an exception
                 Key: PHOENIX-5107
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5107
             Project: Phoenix
          Issue Type: Bug
            Reporter: Chinmay Kulkarni


Steps to repro:

 

{{create immutable table t1 (a varchar, b integer primary key) IMMUTABLE_STORAGE_SCHEME =
SINGLE_CELL_ARRAY_WITH_OFFSETS, COLUMN_ENCODED_BYTES = 1;}}
{{upsert into t1 (a, b, dyn1 integer) values('ready', 10, 3);}}
{{upsert into t1 (a, b, dyn1 integer, dyn2 varchar) values('steady', 20, 4, 'chinmay');}}
{{upsert into t1 (a, b, dyn1 integer, dyn2 varchar, dyn3 integer) values('go', 30, 5, 'kulkarni',
7);}}
{{select a, b, dyn1, dyn2 from t1 (dyn1 integer, dyn2 varchar);}}

 

The select query above throws the underlying exception:
