--------------------------------------------
Summary: Expose table and partition metadata over HMS API
Key: IMPALA-10613
URL: https://issues.apache.org/jira/browse/IMPALA-10613
Project: IMPALA
Issue Type: Sub-task
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
Catalogd caches the table and partition metadata. If an external FE needs to be
supported to query using the Impala, it would need to get this metadata from
catalogd to compile the query and generate the plan. While a subset of the
metadata which is cached in catalogd, is sourced from Hive metastore, it also
caches file metadata which is needed by the Impala backend to create the Impala
plan. It would be good to expose the table and partition metadata cached in
catalogd over HMS API so that any Hive metastore client (e.g spark, hive) can
potentially use this metadata to create a plan. This JIRA tracks the work
needed to expose this information over catalogd.
