postAnalyze

public void postAnalyze(HiveSemanticAnalyzerHookContext context,
               List<Task<? extends Serializable>> rootTasks)
                 throws SemanticException

Description copied from interface: HiveSemanticAnalyzerHook

Invoked after Hive performs its own semantic analysis on a statement (including optimization). Hive calls postAnalyze on the same hook object as preAnalyze, so the hook can maintain state across the calls.

Specified by:

postAnalyze in interface HiveSemanticAnalyzerHook

Overrides:

postAnalyze in class AbstractSemanticAnalyzerHook

Parameters:

context - context information for semantic analysis

rootTasks - root tasks produced by semantic analysis; the hook is free to modify this list or its contents

Throws:

SemanticException

authorizeDDL

protected void authorizeDDL(HiveSemanticAnalyzerHookContext context,
                List<Task<? extends Serializable>> rootTasks)
                     throws SemanticException

Checks for the given rootTasks, and calls authorizeDDLWork() for each DDLWork to be authorized. The hooks should override this, or authorizeDDLWork to perform the actual authorization.

Throws:

SemanticException

authorizeDDLWork

protected void authorizeDDLWork(HiveSemanticAnalyzerHookContext context,
                    Hive hive,
                    DDLWork work)
                         throws HiveException

Authorized the given DDLWork. Does nothing by default. Override this and delegate to the relevant method in HiveAuthorizationProvider obtained by getAuthProvider().

Throws:

HiveException

authorize

protected void authorize(Privilege[] inputPrivs,
             Privilege[] outputPrivs)
                  throws AuthorizationException,
                         SemanticException

Throws:

authorizeTable

protected void authorizeTable(Hive hive,

                  Privilege priv)
                       throws AuthorizationException,
                              HiveException

Throws:
