> Copy constructor of ImmutableBytesWritable needs to consider the offset
> -----------------------------------------------------------------------
>
> Key: HBASE-9427
> URL: https://issues.apache.org/jira/browse/HBASE-9427
> Project: HBase
> Issue Type: Bug
> Reporter: Vasu Mariyala
>
> A simple test below
> {code}
> byte[] bytes = {'a','b','c','d','e','f'};
> ImmutableBytesWritable writable1 = new ImmutableBytesWritable(bytes, 1,
> bytes.length);
> ImmutableBytesWritable writable2 = new ImmutableBytesWritable(writable1);
> Assert.assertTrue("Mismatch", writable1.equals(writable2));
> {code}
> would fail with AssertionFailedError.
> The reason for this is
> {code}
> public ImmutableBytesWritable(final ImmutableBytesWritable ibw) {
> this(ibw.get(), 0, ibw.getSize());
> }
> {code}
> the constructor would always assume 0 as the offset while it can get it from
> ibw.getOffset() method.
