             Summary: Turn on local-catalog mode by default
                 Key: IMPALA-13947
                 URL: https://issues.apache.org/jira/browse/IMPALA-13947
             Project: IMPALA
          Issue Type: Task
          Components: Catalog
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


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.
