----------------------------------------
Summary: Make CachingHTableFactory thread-safe for 0.98 branch
Key: PHOENIX-4025
URL: https://issues.apache.org/jira/browse/PHOENIX-4025
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.11.0
Reporter: Geoffrey Jacoby
Assignee: Geoffrey Jacoby
Fix For: 4.12.0
CachingHTableFactory, which is used in global index writes, isn't thread-safe
(see discussion in PHOENIX-4021) and will be removed in the master and
4.x-HBase-1.x branches. However, according to PHOENIX-3159 it's still needed in
HBase 0.98-based Phoenix because creating HTables is still heavy-weight in
0.98.
This means it needs to be made thread-safe. Current plan is when an HTable's
requested, check the reference count (which is already tracked for cleanup
purposes) and if the count is 1, create a new HTable. We'll cache lists of
identical HTables per HBase table, rather than 1 HTable per HBase table.
