Hi! I was trying out different arithmetic functions in SparkSql. I noticed a weird thing. While *sinh* and *tanh* functions are working, using *cosh* results in an error saying:
*Exception in thread "main" org.apache.spark.sql.AnalysisException: undefined function cosh;* The documentation says *cosh* is implemented since 1.4 and I also find it weird that since *tanh* and *sinh* are implemented (and working) why would *cosh* fail. I looked for it on jira but could not find any related bug. Could someone confirm if this is an actual issue or something wrong on my part. Query I am using: SELECT cosh(`age`) as `data` FROM `table` Spark Version: 10.4 SparkSql Version: 1.5.1 I am using the standard example of (name, age) schema (though I am setting age as Double and not Int as I am trying out maths functions). The entire error stack can be found here <http://pastebin.com/Tc7BQkCm>. Thanks! Shagun
