Uma Maheswara Rao G updated HADOOP-9505:
----------------------------------------
Description:
I have created a file with checksum disable option and I am seeing
ArrayIndexOutOfBoundsException.
{code}
out = fs.create(fileName, FsPermission.getDefault(), flags, fs.getConf()
.getInt("io.file.buffer.size", 4096), replFactor, fs
.getDefaultBlockSize(fileName), null, ChecksumOpt.createDisabled());
{code}
See the trace here:

In FSOutputSummer#int2byte will not check any bytes length, so, do you think we
have to to check the length then only we call this in CRC NULL case, as there
will not be any checksum bytes?
{code}
static byte[] int2byte(int integer, byte[] bytes) {
bytes[0] = (byte)((integer >>> 24) & 0xFF);
bytes[1] = (byte)((integer >>> 16) & 0xFF);
bytes[2] = (byte)((integer >>> 8) & 0xFF);
bytes[3] = (byte)((integer >>> 0) & 0xFF);
return bytes;
}
{code}

Whether I have missed any other configs to set?
