Pengcheng Xiong commented on HIVE-15300:
----------------------------------------
[~rajesh.balamohan], i just took a look. It seems that we need to catch the
exception following the similar way used in other places in SemanticAnalyzer.
Just like this
{code}
Table tab = null;
try{
tab = getTableObjectByName(tabName);
} catch (HiveException e) {
LOG.info("Table " + tabName + " is not found.");
}
{code}
Could u resubmit the patch? Thanks.

> E.g Q88 in tpc-ds takes lots of time to compile and it ends up getting the
> table details for the same table repeatedly. It took 20+seconds to compile
> the query.
> It would be good to reuse the table information in
> SemanticAnalyzer::getMetadata.
