Impala Auto Update Metadata Support

Impala Auto Update Metadata Support

There are lots of CDH users requested that Impala to support automatic metadata update, so that they do NOT need to run “INVALIDATE METADATA” every time when create table or data are updated through other components, like Hive or Pig.

I would like to share that this has been reported upstream and tracked via JIRA: IMPALA-3124. Currently it is still not fixed and it requires detailed design to make sure that it will work in the proper way.

There is no ETA at this stage on when this feature will be added. Advise anyone interested on this feature to add comments to the JIRA. The more votes, the better chance that it will be prioritized.

Hope above information is helpful.
