Hi all,
I have 5 region servers and this is my config:
Hardware:
2 physical machines -> 7 vitural machines
Each vitural machine:
CPU: 8cores
RAM: 24GB
We are setup hadoop env with hortonwork 2.5 and setup HBase with 5
RegionServer, 2 Hbase masters
Config:
export HBASE_HEAPSIZE=8000
export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -Xms8G -Xmx8g"
When i excecute many queries on the same time, some regions has high CPU
usage (close 100%). So each query is very slow.
Test case:
+ On single request: 3s
+ On 5 requests on same times: (submit multi-requests from client):
20s/request
I would highly appreciate your help.
Thanks
