Constructor & Destructor Documentation

com.cloudera.impala.analysis.CreateUdfStmt.CreateUdfStmt ( FunctionName  fnName, FunctionArgs  args, TypeDef  retTypeDef, HdfsUri  location, boolean  ifNotExists, HashMap< CreateFunctionStmtBase.OptArg, String >  optArgs  )

inline

Builds a CREATE FUNCTION statement

Parameters

fnName	- Name of the function
fnArgs	- List of types for the arguments to this function
retType	- The type this function returns.
location	- Path in HDFS containing the UDA.
ifNotExists	- If true, no errors are thrown if the function already exists
additionalArgs	- Key/Value pairs for additional arguments. The keys are validated in analyze()
