---------------------------------------

             Summary: After PHOENIX-3271 higher memory consumption on RS leading to OOM/abort
on immutable index creation with multiple regions on single RS
                 Key: PHOENIX-3649
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3649
             Project: Phoenix
          Issue Type: Bug
            Reporter: Mujtaba Chohan


*Configuration*
hbase-0.98.23 standalone
Heap 5GB

*When*
Verified that this happens after PHOENIX-3271 Distribute UPSERT SELECT across cluster. https://git-wip-us.apache.org/repos/asf?p=phoenix.git;a=commitdiff;h=accd4a276d1085e5d1069caf93798d8f301e4ed6

To repro
{noformat}
CREATE TABLE INDEXED_TABLE (HOST CHAR(2) NOT NULL,DOMAIN VARCHAR NOT NULL, FEATURE VARCHAR
NOT NULL,DATE DATE NOT NULL,USAGE.CORE BIGINT,USAGE.DB BIGINT,STATS.ACTIVE_VISITOR INTEGER
CONSTRAINT PK PRIMARY KEY (HOST, DOMAIN, FEATURE, DATE)) IMMUTABLE_ROWS=true,MAX_FILESIZE=30485760
{noformat}
Upsert 2M rows (CSV is available at https://goo.gl/OsTSKB) that will create ~4 regions on
a single RS and then create index with data present
{noformat}
CREATE INDEX idx5 ON INDEXED_TABLE (CORE) INCLUDE (DB,ACTIVE_VISITOR)
{noformat}

Prior to the change index creation succeeds with as little as 2GB heap.
