hi,all:
I wan't to sychronize hive metadata, if one table was added or alter I can
be notified , I know there is a HiveMetaHook interface , but it exactly was not
a hook.

is this the reason ?
code in Optimizer.java
if (postExecHooks.contains("org.apache.hadoop.hive.ql.hooks.PostExecutePrinter")
||
postExecHooks.contains("org.apache.hadoop.hive.ql.hooks.LineageLogger")) {
transformations.add(new Generator());
}

I write a log on org.apache.hadoop.hive.ql.Driver : LOG.info("Driver:1866 : "
+ hookContext.getIndex().getFinalSelectOps().size());
if I config LineageLogger to the log will out put 1 or
it will out put 0 , why ??

t
put full lineage log.
I note that ,if I only config MyLineageLogger , LinkedHashMap>
finalSelOps = index.getFinalSelectOps();
will return 0
