----------------------------------
Summary: Support invalidate meta cache when some tables never
visit again
Key: HBASE-29401
URL: https://issues.apache.org/jira/browse/HBASE-29401
Project: HBase
Issue Type: Improvement
Components: meta
Reporter: chaijunjie
There are one senior:
we have 2 apps to read/write HBase tables for a long time...
we could condisder as APP1 and APP2
APP1 create a new HBase table everyday, and write some data to it, then never
write/read it, it is just a daily-table(temporary table)...
APP2 will drop old table(before 30 days)....
Then the metaCache in APP1's conn, will contains too many old tables's region
locations...even never clear these after the table dropped...only when we
create a new hbase conn, will decrease memory used...
when we drop table using another conn(APP), will cause memleak on other APP's
metacache...
we could not to control to invalidate meta cache when some tables never visit
again...
