--------------------------------
Summary: OM keyTable and fileTable are not interchangeable
Key: HDDS-6426
URL: https://issues.apache.org/jira/browse/HDDS-6426
Project: Apache Ozone
Issue Type: Sub-task
Components: OM
Reporter: Ethan Rose
HDDS-5835 changed OMMetadataManager#getKeyTable to return a different table
based on the bucket layout: fileTable for FSO buckets, keyTable otherwise. The
problem is that these two tables have completely different sets of keys and key
formats. It is not enough to change existing requests expecting to operate on
the key table to now point to the file table if they are invoked on an FSO
bucket, because they will query the table with the wrong key format.
This implementation is misleading for developers (you ask for a keyTable and
might get a fileTable instead) and caused HDDS-6414, while possibly masking
other similar bugs for existing requests. This Jira is to consider a less
error-prone approach.
