Impala isn't technically Cloudera only, it's open source (https://github.com/cloudera/impala), and other people have gotten it to run on their Hadoop distribution, but since it's developed by Cloudera, it was developed to run on the CDH platform (Hadoop). Parquet was a joint effort between Cloudera and Twitter, and now it's being developed by many other companies. You can use it with Hive, Pig, MapReduce, Cascading, Crunch and I think Apache Drill's first milestone has adopted it as a columnar format as well. Parquet also allows you to use your Avro or Thrift schema (soon Protobuffs) to write Parquet data, too. It's a separate project in the ecosystem and has its own roadmap (https://github.com/Parquet/parquet-mr).

Agreed, and some of these databases don't even embrace it. For example, HBase's main website makes no mention of being a "NoSQL" database (http://hbase.apache.org/). Of course, given the right circumstances, you could totally use SQL to talk to your data which lives in HBase, but that doesn't make it a SQL database. SQL is a query language, a database is usually made up of many different components, one of them usually being a query engine. Look at Impala (https://github.com/cloudera/impala) which decouples itself completely from the storage engine layer, it can query data CSV data, doesn't mean it's a SQL database.
