----------------------------------------
Summary: Import from oracle using oraoop with map-column-java to
avro fails if special characters encounter in table name or column name
Key: SQOOP-3123

Project: Sqoop
Issue Type: Bug
Components: connectors/oracle
Affects Versions: 1.4.6, 1.4.7
Reporter: Dmitry Zagorulkin
I'm trying to import data from oracle to avro using oraoop.
My table:
{code}
CREATE TABLE "IBS"."BRITISH#CATS"
( "ID" NUMBER,
"C_CODE" VARCHAR2(10),
"C_USE_START#DATE" DATE,
"C_USE_USE#NEXT_DAY" VARCHAR2(1),
"C_LIM_MIN#DAT" DATE,
"C_LIM_MIN#TIME" TIMESTAMP,
"C_LIM_MIN#SUM" NUMBER,
"C_OWNCODE" VARCHAR2(1),
"C_LIMIT#SUM_LIMIT" NUMBER(17,2),
"C_L@M" NUMBER(17,2),
"C_1_THROW" NUMBER NOT NULL ENABLE,
"C_#_LIMITS" NUMBER NOT NULL ENABLE
) SEGMENT CREATION IMMEDIATE

TABLESPACE "WORK" ;
{code}
My first script is:
{code}
./sqoop import \
-Doraoop.timestamp.string=false \
--direct \
--connect jdbc:oracle:thin:@localhost:49161:XE \
--username system \
--password oracle \
--table IBS.BRITISH#CATS \
--target-dir /Users/Dmitry/Developer/Java/sqoop/bin/imported \
--as-avrodatafile \
--map-column-java
ID=String,C_CODE=String,C_USE_START#DATE=String,C_USE_USE#NEXT_DAY=String,C_LIM_MIN#DAT=String,C_LIM_MIN#TIME=String,C_LIM_MIN#SUM=String,C_OWNCODE=String,C_LIMIT#SUM_LIMIT=String,C_L_M=String,C_1_THROW=String,C_#_LIMITS=String
{code}
fails with
{code}
2017-01-13 16:11:21,348 ERROR [main] tool.ImportTool (ImportTool.java:run(625))
- Import failed: No column by the name C_LIMIT#SUM_LIMITfound while importing
data; expecting one of [C_LIMIT_SUM_LIMIT, C_OWNCODE, C_L_M, C___LIMITS,

C_LIM_MIN_TIME, C_USE_USE_NEXT_DAY]
{code}
After i've found that sqoop has replaced all special characters with
underscore. My second script is:
{code}
./sqoop import \
-D oraoop.timestamp.string=false \
--direct \
--connect jdbc:oracle:thin:@localhost:49161:XE \
--username system \
--password oracle \

I've found that old problem and "oraoop.timestamp.string=false" must solve it,
but it does not.
What do you think?
Also please assign this problem to me.
