HBase on Tachyon/alluxio

Hi, did anyone consider running HBase on top of http://www.alluxio.org/ ?
Does it make sense?

Read-only? No write-through?

So, let Tachyon take care of rehydration -- pulling from HDFS back up into
Tachyon tier?

You mean, giving hbase a tachyon URL rather than HDFS?

HBase can digest different URLs -- file, s3, etc.  Just needs to be a
provider.

Have you tried it? Would be interesting to hear how it works out.

One potential usecase:
you load data to HBase using BulkLoader, skipping regular WAL write path.
then you serve loaded data for reading.

If Tachyon/alluxio fails who cares? Anyway data is on HDFS. The only thing
to consider is to correctly switch from Tachyon/alluxio file url to regular
HDFS url.
