Hi Varun,
Can you try changing the java code like this -
public void set_type(String type) {
this.type = new String(type.getbytes(),"UTF8");
}
public QueryResult with_type(String type) {
this.type = new String(type.getbytes(),"UTF8");
return this;
}
Thanks
Sumit

Thanks Jarcec.
sqoop version is 1.4.2
I was verifying the QueryResult.java file that sqoop creates; type is the
column name which has multi-byte data(utf-8).
Does declaring type as string work for multi-byte data?
grep type QueryResult.java
private String type;
public String get_type() {
return type;
public void set_type(String type) {
this.type = type;
public QueryResult with_type(String type) {
this.type = type;
equal = equal && (this.type == null ? that.type == null :
this.type.equals(that.type));
this.type = JdbcWritableBridge.readString(5, __dbResults);
JdbcWritableBridge.writeString(type, 5 + __off, 12, __dbStmt);
this.type = null;
this.type = Text.readString(__dataIn);
if (null == this.type) {
Text.writeString(__dataOut, type);
__sb.append(FieldFormatter.escapeAndEnclose(type==null?"\\N":type
(file://n%22:type/), delimiters));
if (__cur_str.equals("null")) { this.type = null; } else {
this.type = __cur_str;
__sqoop$field_map.put("type", this.type);
else if ("type".equals(__fieldName)) {
this.type = (String) __fieldVal;

Thank you Varun,
the sequence c3 83 c2 a9 indeed do not correspond to correct character. I was
able to google out one entry in stack overflow [1] that might be relevant to
your issue somehow. I've tried to reproduce this on my cluster, but I was not
able to. Do you think that you can do mysqldump of the table in question? If
you could share it with the Sqoop version and exact command line I would like
to explore that a bit.
