Eric Hanson commented on HIVE-5517:
-----------------------------------

I discovered that in vectorized mode, the function log(base, column) is implemented incorrectly as log(column, base). I will fix that issue in this JIRA.

> Vectorized implementations of string functions, math functions, and type casts have been implemented.
> Currently, these have junit tests to verify input/output correctness on batches of rows. They have been tested from the command line to verify end-to-end execution. However, we should add end-to-end tests to verify they work from SQL statements and produce the right results. This will catch regressions in case of, for example, incorrect changes in VectorizationContext.java.
