------------------------------------
Summary: Use a shared thread pool for AtomicityWriter,
AtomicGetReader, AtomicScanReader's connections in TestAcidGuarantees
Key: HBASE-17792
URL: https://issues.apache.org/jira/browse/HBASE-17792
Project: HBase
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: huaxiang sun
Assignee: huaxiang sun
Priority: Minor
AtomicityWriter, AtomicGetReader, AtomicScanReader creates connection inside,
since the thread pool is not shared, by default each connection will create 256
threads. If there are 5 AtomicityWriters, 1 AtomicGetReader, and 1
AtomicScanReader, it will create lots of threads and causes max user processes
to be reached, and OOME. Use a share thread pool to work around this issue.
