Subbu M Iyer commented on HBASE-4025:
-------------------------------------
May be we should create all tables under /hbase/tables/<table name> instead of
/hbase/<table name> so that we can avoid future cases where we create other
folder under /hbase such as .logs,.corrupt et al that does not contain table
descriptors?
So, this pattern will have some thing like:
/hbase/.logs
/hbase/.corrupt
/hbase/.oldlogs
/hbase/.META.
/hbase/-ROOT-
/hbase/<future non user system folders>
/hbase/UserTables/<user table folder>/.tableinfo
and when we need to retrieve all the table descriptors we simply iterate over
the /hbase/UserTables folder rather than the /hbase and ignore all system
folders.
Other option would be:
/hbase/System/.logs, .oldlogs, .corrupt et al.
/hbase/UserTables/<user tables>
This way we can avoid adding a band-aid fix to this read table descriptor logic
every time we have a new system folder.
thoughts?
