Is Hbase schema on read?

I am new to hbase . I know that HBase is key/value store which stores the data in array of bytes. couple of queries

  1. Does Hbase support data types for columns ?
  2. Is Hbase schema on read (like hive ) or write ?

For the first question , I saw couple of links and got confused.

  1. Natively HBase does not support data types for columns everything is treated as byte arrays. Here is an excert from hbase book on supported data types. But you could use high level frameworks like phoenix and here are its supported data types.

  2. As HBase is schema-less I would say HBase relies on schema on read mechanism.
