>          Issue Type: Bug
>    Affects Versions: 1.4.6
>            Reporter: Szabolcs Vasas
>            Assignee: Szabolcs Vasas

> The following Sqoop command fails with a javac error:
> {code}
> sqoop import --connect $MYCONN --username $MYUSER --password $MYPSWD --query "select
C1_INT,C4_VARCHAR20, REGEXP_REPLACE(TRIM(C4_VARCHAR20),'\:','!') from T1_IMPORT WHERE \$CONDITIONS"
--target-dir regex_imp --delete-target-dir -m 1
> {code}
> The reason is that the REGEXP_REPLACE expression contains a backslash character which
does not get escaped in ClassWriter and an invalid string gets generated into the Java code.
> SQOOP-2864 solved this problem for the double quote character we need to generalize that
solution.
