Sqoop - Issue with BlobRef object cloning

[Swati Ambulkar -X (sambulka - PERSISTENT SYSTEMS INC at Cisco)]

Hi All:

Has anyone used sqoop  successfully for BLOB data import and merge?
I am running into this issue when trying to clone a BlobRef object for merging 
after incremental import:
Getting CloneNotSupportedException : highlighted clone call and other details 
below:

public Object clone() throws CloneNotSupportedException {
    QueryResult o = (QueryResult) super.clone();
    o.LOBOBJECT = (o.LOBOBJECT != null) ? (com.cloudera.sqoop.lib.BlobRef) 
o.LOBOBJECT.clone() : null;
    o.LAST_UPDATE_DATE = (o.LAST_UPDATE_DATE != null) ? (java.sql.Timestamp) 
o.LAST_UPDATE_DATE.clone() : null;
    return o;
  }

LobRef.class (decompiled source) :
Source Code ( #108-113) 
http://grepcode.com/file/repository.cloudera.com/content/repositories/releases/org.apache.sqoop/sqoop/1.4.3-cdh4.3.0/org/apache/sqoop/lib/LobRef.java?av=f


public Object clone() throws CloneNotSupportedException {
    LobRef r = (LobRef)super.clone();   
<-----------------------------------Throws exception
    r.lobReader = null;
    if(null != this.realData) {
        r.realData = this.deepCopyData(this.realData);
    }

    return r;
}
