-------------------------------------
Summary: RCFile parser ignores escape characters
Key: IMPALA-7778
URL: https://issues.apache.org/jira/browse/IMPALA-7778
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 3.0, Impala 2.11.0, Impala 2.10.0, Impala 2.9.0,

Reporter: Tim Armstrong
If an RCFile table has an escape character specified then it is ignored by
Impala.
{code}
-- HIVE
CREATE TABLE rc_escape ( s string)
ROW FORMAT delimited fields terminated by ',' escaped by '\\'
STORED AS RCFILE;
insert into rc_escape select '\\"';
select length(s), s from rc_escape;
-- +-----+-----+
-- | c0 | s |
-- +-----+-----+
-- | 2 | \" |
-- +-----+-----+
-- IMPALA
invalidate metadata rc_escape;
select length(s), s from rc_escape;
-- +-----------+-----+
-- | length(s) | s |
-- +-----------+-----+
-- | 3 | \\" |
-- +-----------+-----+
{code}
I reproduced on my dev env with "beeline -n $USER -u
jdbc:hive2://localhost:11050/default" for Hive and "impala-shell" for Impala.
