sqoop EXPORT - There is no column found in the target table - export

Question

I wrote a simple script to create a user (TestV100), create a table (Xy100) in that schema and export a tabl delimited flat file from hadoop to this oracle table.
This is the shell script: - ExportOracleTestV100.sh
#!/bin/bash
# Testing connectivity to Oracle DB
#sqoop eval --connect jdbc:oracle:thin:#hostname:1521:orcl -username test -password password --query "SELECT count(*) as bob FROM \"TestV1\".\"Test\"" --verbose
HOST=$1
USER=$2
PASS=$3
SCHEMA=$4
PORT=$5
SID=$6
SQOOP=/usr/bin/sqoop
JDBC="jdbc:oracle:thin:#$1:$5:$6"
SQOOP_EVAL="$SQOOP eval --connect $JDBC --username $USER --password $PASS --query"
#Create Schema and Tables;
${SQOOP_EVAL} "CREATE USER \"TestV100\" identified by \"password\""
${SQOOP_EVAL} "GRANT CONNECT TO \"TestV100\""
${SQOOP_EVAL} "ALTER USER \"TestV100\" QUOTA UNLIMITED ON USERS"
${SQOOP_EVAL} "DROP TABLE \"TestV100\".\"Xy100\""
${SQOOP_EVAL} "CREATE TABLE \"TestV100\".\"Xy100\"( \"a\" NVARCHAR2(255) DEFAULT NULL, \"x\" NUMBER(10,0) DEFAULT NULL, \"y\" NUMBER(10,0) DEFAULT NULL )"
############################
## Load Data into tables; ##
############################
SQOOP_EXPORT="/usr/bin/sudo -u hdfs $SQOOP export --connect ${JDBC} --username $USER --password $PASS --export-dir"
${SQOOP_EXPORT} "/tmp/rv/TestV100/xy100.txt" --table "\"\"$SCHEMA\".\"Xy100\"\"" --fields-terminated-by "\t" --input-null-string null -m 1
And this is the input file: - cat /tmp/rv/TestV100/Xy100.txt
c 8 3
a 1 4
c 6 1
c 2 0
a 7 7
c 4 2
c 7 5
a 0 0
c 5 6
a 2 2
a 5 5
a 3 6
c 9 7
a 4 1
c 3 4
a 6 3
b 6 5
b 8 7
b 5 1
b 7 3
b 2 4
b 1 0
b 4 6
b 3 2
This is how the shell script is called:
sh ./ExportOracleTestV100.sh oracle11 test password TestV100 1521 orcl --verbose
Note: 'test' user has full access on TestV100 schema.
Output:
[root#abc-repo-app1 rv]# sh ./ExportOracleTestV100.sh oracle11 test password TestV100 1521 orcl --verbose

As you can see above, Sqoop version is 1.4.5-cdh5.4.1
I somehow managed to get it this far. I see a lot of posting online for sqoop import and this error, and solution is to change the table name to UPPERCASE in the command. But, I am running export. Also, the oracle table HAS to be created with mixed case.
I hope I gave all required information here. Can someone please help or point to some place which can help me get past this error?

Answer 1

table name in uppercase worked.
sqoop export --connect jdbc:oracle:thin:#xyzx:1569:xyz --username xyz --password xyz --table CIPHADOOPCUSTOMERREPORT --export-dir /apps/hive/warehouse/ciprpt.db/dtd_customer_report --input-fields-terminated-by "\t" --input-lines-terminated-by "\n" --verbose -m 8 --input-null-string '\N' --input-null-non-string '\N'

Answer 2

Supply the table name in upper case in the --table argument.
Sounds silly but yeah - works with table name in upper caps.

Answer 3

I had this problem because target table for sqoop export was one column short.
Solution:
specify list of columns with --columns parameter; or regenerate target table to match schema of the input table.
