MultiAction fails on 0.92.0 about asynchbase HOT 7 CLOSED

Interesting, it looks like the RegionServer is trying to deserialize attributes, but asynchbase doesn't send any, so that shouldn't happen.

The good news is that I can reproduce this, so the fix should be easy.

Thanks for the bug report, this is fixed by StumbleUponArchive/asynchbase@7100f8a

It was a stupid mistake due to the fact that, surprisingly, I never tested a multi RPC composed solely of DeleteRequest. I always had a mix of DeleteRequest and PutRequest.

Thanks for the quick fix. I'm just going to test it.

There seems to be another issue while serializing a MultiAction:

Can you open a new issue please?

It appears that you're trying to use an empty column family name. I don't think HBase supports it. I'll check with HBase devs today. If it's not allowed, I'll have asynchbase throw an exception back.

I use following method

public DeleteRequest(final byte[] table, final byte[] key) {
    this(table, key, null, null, KeyValue.TIMESTAMP_NOW, RowLock.NO_LOCK);
}

Using this method you set the family to

static final byte[] WHOLE_ROW = new byte[0];
