What Are The Drawbacks Of Impala?

1.	What Are The Drawbacks Of Impala?
Answer» Impala isn't a GA OFFERING yet. So as a beta offering, it has SEVERAL limitations in terms of functionality and capability; for EXAMPLE, several of the data sources and file formats aren't yet supported. LSO ODBC is currently the only client driver that's available, so if we have JDBC applications we are not able to use them directly yet. Another Impala drawback is that it's only available for use with Cloudera's distribution of Hadoop; that is CDH 4.1
