huaxiang sun created HBASE-17792: ------------------------------------ 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
