Enis Soztutar commented on HBASE-8015:
--------------------------------------
bq. I've also changed the tableDir on hdfs to include namespace as the parent
directory
How do you plan to enforce this? WAL's completely bypass the quota, and if a
ns's quota fills up, it cannot flush, and compact, which will affect all of the
other namespaces. I am not against the idea of having a parent namespace dir
for tables, but just wondering whether this is really feasible. Can't we
enforce quotas at the HBase level, since we are doing ACL's at the application
layer for the same reasons.
