In-Depth Information
Summary
By end of this chapter we have covered various SQL statements written using Impala
Query Language, which can be used either with the Impala shell or directly from a web
interface. When applicable, we have provided small examples of SQL statements, be-
cause in the next chapter we will take the learning from this and the previous chapters
into a full-scale example, and apply these SQL statements to load data from HDFS
and then run queries on it. By the time this topic was ready in print, Impala 1.2.0 Beta
was released with new features. It is possible that some of the features written in this
chapter either work differently or require more attention. Please check the Cloudera
documentation for more information regarding this.
