Problem with receiveFile method

[cihadoge]

When I call the receiveFile method with offset different than 0, it removes all the data before the offset.

Has anyone faced with this issue ?

Here is my code snippet

// We need to set file length as original file length
RandomAccessFile raf = new RandomAccessFile("download.tmp", "rw");
raf.setLength(originalFileLength);
raf.close();

File receivedFile = new File("download.tmp");
client.receiveFile(receivedFile, offset, length);
client.close();

hello, I want to change the protocol of the datanode(hadoop) to UDT, I am working on the barchart-udt.However I recieved a problem in saslHandShake that the Server can not read a integer.I saw the packet log with tcpdump on server and found when the client send the SASL_TRANSFER_MAGIC_NUMBER,there are many bad checksum:

00:54:50.334452 IP (tos 0x0, ttl 64, id 41646, offset 0, flags [DF], proto UDP (17), length 68)
    server addr.1002 > client addr.56895: [bad udp cksum 0x6833 -> 0x0de2!] UDP, length 40
00:54:50.335248 IP (tos 0x0, ttl 64, id 41647, offset 0, flags [DF], proto UDP (17), length 48)
    server addr.1002 > client addr.56895: [bad udp cksum 0x681f -> 0xf102!] UDP, length 20
