> This aims to turn on local-catalog mode by default.
> One behavior change is FileSystem permission checks will be defered to the 
> execution stage (IMPALA-7539). Note that in the legacy catalog mode, 
> permission checks are done in planning stage so illegal queries can fail 
> before execution. But preloading all the dir/file permissions is found to be 
> a bottleneck of metadata loading on large tables. So we decided to skip it in 
> IMPALA-12929.
