Enis Soztutar created HBASE-12035:
-------------------------------------
Summary: Client does an RPC to master everytime a region is
relocated
Key: HBASE-12035
URL: https://issues.apache.org/jira/browse/HBASE-12035
Project: HBase
Issue Type: Improvement
Reporter: Enis Soztutar
Fix For: 2.0.0
HBASE-7767 moved table enabled|disabled state to be kept in hdfs instead of
zookeeper. isTableDisabled() which is used in
HConnectionImplementation.relocateRegion() now became a master RPC call rather
than a zookeeper client call. Since we do relocateRegion() calls everytime we
want to relocate a region (region moved, RS down, etc) this implies that when
the master is down, the some of the clients for uncached regions will be
affected.
See HBASE-7767 and HBASE-11974 for some more background.
