Zheng Wang created HBASE-27805: ---------------------------------- Summary: The chunk created by mslab may cause memory fragement and leading to fullgc Key: HBASE-27805 URL: https://issues.apache.org/jira/browse/HBASE-27805 Project: HBase Issue Type: Improvement Components: regionserver Reporter: Zheng Wang Assignee: Zheng Wang
The default size of chunk is 2MB, when we use G1, if heapRegionSize equals 4MB, these chunks are allocated as humongous objects, exclusively allocating one region, then the remaining 2MB become memory fragement. Lots of memory fragement may leading to fullgc even if the percent of used heap not high enough. -- This message was sent by Atlassian Jira (v8.20.10#820010)
