Hi Michael. Impala also has support for querying HBase. As far as I'm aware we have not seen any demand for querying other non-Hadoop systems like MySQL (which of course has its own query parser and execution anyway).

Indeed. That is the beauty of Apache Drill. Not only the flexibility concerning the data formats supported, but also the type of storage. Impala is confined to HDFS(-based stuff), in Apache Drill you can use HBase or MySQL or CouchDB or GǪ

re: Cloudera Impala Brings SQL Querying To Hadoop
Doug, thank you for your write-up! I wonder why you can't be bothered to invest the two minutes to also provide a link to Apache Drill? It's http://incubator.apache.org/dr... for the record and you're welcome.

Secondly, I find it poor research to state that Apache Drill == MapR. Yes, we're certainly supporting it, however, in case you haven't figured it yet, it's an *Apache* Incubator project that is driven and defined by the community, MapR being part of it. See also one of my recent status reports at https://speakerdeck.com/mhause... containing a shout out to some of the core contributors (yes, with two people from MapR, alright, I'm not hiding the fact).

Look, I give it Cloudera that they have made Impala now GA, but it's funny to learn that they avoided the 'hard way' (achieving community consensus on the APIs via Apache) and shipped a proprietary product. I believe in the power of open APIs and that's why I think, Apache Drill will be successful, eventually. As an additional fun fact: ask Oracle why they don't ship Impala as part of their partnership with Cloudera?

Cheers,
Michael

re: Cloudera Impala Brings SQL Querying To Hadoop
Another weakness of Impala, according to competitors, is flexibility in handing a range of data formats. Countering this claim, Cloudera talked up support for both Parquet (compression) and Avro-supported file formats. Any data wonks have comment on whether Cloudera has effectively addressed the need for handling a variety of data formats?

Cloudera remains focused and out front on tools that help users adopt Hadoop.If its Impala has a true performance advantage, that will tend to keep it out front. Time and user experience will tell. Charlie Babcock, editor at large, InformationWeek

Kudos to Cloudera for getting there first, it's a step in the right direction.
