Vincent Poon updated PHOENIX-4382: ---------------------------------- Summary: Immutable table variable length column values starting with separator byte return null in query results (was: Certain immutable table variable length column values may return null in query results) > Immutable table variable length column values starting with separator byte > return null in query results > ------------------------------------------------------------------------------------------------------- > > Key: PHOENIX-4382 > URL: https://issues.apache.org/jira/browse/PHOENIX-4382 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.14.0 > Reporter: Vincent Poon > Assignee: Vincent Poon > Attachments: PHOENIX-4382.v1.master.patch, > PHOENIX-4382.v2.master.patch, UpsertBigValuesIT.java > > > For immutable tables, upsert of some values like Short.MAX_VALUE results in a > null value in query resultsets. Mutable tables are not affected. I tried > with BigInt and got the same problem. > For Short, the breaking point seems to be 32512. > This is happening because of the way we serialize nulls. For nulls, we write > out [separatorByte, #_of_nulls]. However, some data values, like > Short.MAX_VALUE, start with separatorByte, we can't distinguish between a > null and these values. Currently the code assumes it's a null when it sees a > leading separatorByte, hence the incorrect query results. > See attached test - testShort() , testBigInt() -- This message was sent by Atlassian JIRA (v6.4.14#64029)
